There are two different types of force: contact, and non-contact. A contact force is a force which touches an object (for example the push force from kicking a soccer ball, and a non-contact force is a force which acts from a distance (for example gravity and magnetism). The unit for measuring force is Newton. Any movement needs a push, pull or twist to start. Some of these forces have special names based on the circumstances; for example buoyancy, thrust, friction, drag, lift and reaction force. ]]> 2018-04-03 01:44:02 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967536 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967589 A force can be a push, pull or twist action, however there are special names for some forces, such as air resistance and buoyancy. Forces are measured in Newtons (N). Forces can also be a contact or non-contact force. Contact forces (including friction) apply force on objects through physical contact, while non-contact forces (including gravity and magnetism) act from a distance. Forces can be balanced an unbalanced. When a force is balanced, the object the force is acting on will not be moving or will move at a constant speed. When a force is unbalanced, the object the force is acting on can start or stop moving and change speeds, direction or shape while moving.]]> 2018-04-03 01:44:25 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967589 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967622 Forces (which are measured in Newtons N) is either a push, pull or twist. It can cause a stationary object to move and a moving object to be stationary. It can slow down or increase the speed of an object and can change the shape of an object. If two forces are opposing each other it could be unbalanced if the net resultant force is anything other than zero and if it is zero , it is balanced.If a force is unbalanced, the object accelerates but if balanced it is either stationary or is moving at a constant speed. Also , all forces have an equal and opposite reaction. Some forces are drag (water resistance , air resistance), friction, reaction force, and more. If there are no reaction forces every structure you stand on will collapse as if the forces is unbalanced, the one with the weaker force is unbalanced. There are also two types of forces, contact and non-contact. The difference between both is one interacts (contact forces) and one doesn't (non-contact forces) .some non-contact forces are gravity, magnetism, static electricity. some contact forces is friction, drag and buoyancy.]]> 2018-04-03 01:44:51 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967622 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967644 A force is a push, pull or twist enacting on an object which forces it to change direction, speed, shape and can cause a stationary object to move.]]> 2018-04-03 01:45:10 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967644 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967655 A force is a push or pull on an object resulting from the object's interaction with another object.

Contact forces involve 2 or more objects whereas non-contact forces involve only 1 object. So many forces are acting on objects especially when not moving. Force is measured in newtons (N) named after Isaac Newton. It is known as a vector quantity. Acceleration is the change in velocity which means it can include slowing down, speeding up or turning around.]]> 2018-04-03 01:45:36 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967680 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967681 There are 2 types of forces. Contact forces and non-contact forces. Contact forces is a force that is physically applied to an object while a non-contact force is a force that acts from a distance. Some examples of forces include thrust, friction, torque, drag, buoyancy, lift and reaction force. The unit of force is measured in N (Newtons).

A non contact force is a force that acts from a distance. Forces are pulling, pushing, or twisting actions that are measured in Newtons (N).

There are 2 types of forces - contact forces and non-contact forces. Forces are measured in Newtons (N). There is usually more than one force acting on an object. If the forces are unbalanced then the object will accelerate. If the forces acting on an object are balanced that is the resultant force is zero, then the object will either be stationary or moving at a steady speed. ]]> 2018-04-03 01:46:09 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967730 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967774 A force is a push that can be measured in newtons. 
A force was something invented by Isaac Newton.]]> 2018-04-03 01:46:31 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967774 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967815 Force is the interaction that contributes to the movement of an object. There are 2 types of force - contact and non-contact, and within these categories of forces are types of forces. Non-contact forces are forces which act on objects without coming into physical contact with it. They include gravity and magnetism. Contact forces are forces which interact with each other and cause movement when two or more objects come into contact with each other. Contact forces include drag, buoyancy and thrust. Force is measured using 'N', which stands for 'Newton' (who discovered most of these theories).]]> 2018-04-03 01:46:59 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967815 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967871 A force can cause an object with mass to change its velocity (ex. acceleration). It can also be described as as a push or pull. The way forces can be measured is through Newtons (N). There are multiple types of forces however if 2 forces go against each other at the same amount of newtons (i.e 100N vs 100N) then it can cancel out, or balance it. The forces can be split into 2 categories - non-contact forces and contact forces. Some examples of non-contact forces include gravity and air resistance. Contact forces can include drag, buoyancy, etc. Forces are not something that happen after a reaction, it is all around us, 24/7. A scenario of forces being used is sitting on a chair. You will use weight force, or gravity to sit and resistance from the ground will keep you up. Because your back is pushing against the chair, air resistance pulls it to you. In conclusion, forces are an important science and should be understood as something that is all around us, keeping the Universe in tact.]]> 2018-04-03 01:47:31 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967871 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967933 A force is a push or a pull acting on an object. Forces are of two types-- Contact and Non-Contact. Forces can slow down, increase the speed or stop a moving object. When a football is kicked it applies a force to it and moves the ball(example). Force is measured in Newtons(N).]]> 2018-04-03 01:48:08 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247967933 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968032 A force is an interaction that is able to change the velocity of an object when the opposite force is weaker. A force can either be a contact force or a non contact force, contact forces interfer directly with an object to change it's velocity (eg. direction, acceleration, etc), while non contact forces act from a distance like gravity or magnetism. The field of a non contact force gets weaker the farther away the object that will be affected is from the source. Examples of contact forces include friction, torque and buoyancy, and examples of non contact forces include gravity and magnetism. Force is measured in Newton (N). Even when an object is not moving forces are applied - like gravity, as it is only when unbalanced force is applied that an object is set into motion, if the forces are balanced they cancel each other out which results in 0 N. ]]> 2018-04-03 01:49:21 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968032 anika9rox https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968117 A force is a push, pull or twist. When there is an unbalance of forces an object accelerates (changes in pace or direction). When forces are balanced, an object is either stationary or moving at a steady pace. Forces are measured in Newtons (N). There are two types of forces. Non-contact forces such as gravity, magnetism and electrostatics and contact forces such as torque, friction, buoyancy, reaction force, thrust, etc.  Non-contact forces act from a distance, and grow weaker over a larger gap. Contact forces are when the force is applied to the object.  ]]> 2018-04-03 01:50:12 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968117 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968121 Forces are measured in Newton
. Force can be either push (an object pushes against an object) or pull (when and object is been pulled), non-contact (doesn't include and contact) or contact (contact is required).]]> 2018-04-03 01:50:16 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968121 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968245 A force is a push, pull or twist motion that can cause an object with mass to change its velocity. Forces can also lead objects into changing direction or speed. There are two types of forces contact forces and non-contact forces. Contact forces such as friction, buoyancy etc, are forces that touch another surface to cause such a force. On the other hand a non-contact force is a force that does not have to touch another surface to act upon it and to create such a force. Non-contact forces are forces such as gravity, magnetism and electrostatics. Such non-contact forces get weaker as they go further away from the source that they are acting on. Force is usually depicted by arrows pointing in the direction that the force is acting upon. If the force on either side or one of several sides is increased, the object moves in the force of the stronger pull, push or twist. This kind of forces are unbalanced forces that are not balanced on any of one of the sides. A balanced force is where both forces are balanced and does not override the other force. In this case the net force or the value of the force is 0n or 0 Newtons. ]]> 2018-04-03 01:51:33 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968245 tlbarnardofs https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968351 A force is a push pull or twist, there are many types of forces including gravitational and gravitational forces. Planes are a great example to demonstrate forces. A plane works like this: There is lift to make the plane go up, and gravity/weight force to make the plane go down, the force out of these which is stronger is the direction where the plane is forced to go to. When the forces balance, planes stabilise. Eventually, if the plane's lift gets too much, it will reach a peak and it will stall. The other 2 forces include thrust and drag. Drag and friction are both "pulls", they hold the plane back, as there are air particles streaming against the plane, and slowing it down. That is the reason planes have a streamline shape, to make them go faster and smoother. The other, last force is thrust. Thrust is controlled by the engine of the plane, which pushes air back to produce a force that pushes it forward. When these forces balance, the acceleration stabilises, and the velocity is constant. The formula to change lift is L=(rho)*(coefficient of lift)*Velocity squared while the formula of Drag is  D=(rho)*(coefficient of Drag)*Velocity squared.
Force is measured by N or newtons.]]> 2018-04-03 01:52:48 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968351 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968419 A force is an interaction which changes the motion of an object, in ways such as push, pull and twist. There are 2 types of forces, contact forces are when objects get in contact with it and cause the force, and non contact forces are when nothing has to touch it, and it is completely natural. I understand that when an object is falling or taking off, it will have lift, drag, and many other things like air resistance or gravitational pull. Forces are measured in Newtons (N), and examples of contact forces are buoyancy and friction, and examples of non contact forces are gravity and magnetism. Gravity and Magnetism happen without any object have to touch it, as friction, an example, requires an object to come in contact with another, to create this.]]> 2018-04-03 01:53:31 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968419 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968467 To summarise, a force is essentially an interaction between two objects or more that come in the form of a push, pull or twist. There are two main types of forces - contact and non contact. Contact force is a when two objects or more's forces interact with one another physically. Contact forces include air resistance, buoyancy, friction, and more. For instance, when a car is driving on the road, a contact force is in motion as the wheels rub against the surface, thus creating friction. Non-contact force is when an object interacts with another's force, without physically contacting each other. One of the main types of non contact forces is gravity.]]> 2018-04-03 01:53:59 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247968467 https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247969774 A force is a push or pull upon an object resulting from the object's interaction with another object]]> 2018-04-03 02:00:23 UTC https://padlet.com/tlbarnardofs/7roqaozuwn0h/wish/247969774
