1.       What is a force?
strength is the physical ability that we apply to something. 

2.       What is a movement? 

movement is the change of position of something in space. 

3.       What sources or types or forces are there in our environment? Mention them. 

the types of force that exist are friction, weight, normal, tension and elastic force. 

4.       When talking about forces in physics how can we analyze the phenomenon of force and movement in our environment? 

The force is in our environment all the time since we humans do not know when we are going to use force and neither when the same environment also uses force, since the environment can also use force in some cases. 

5.       Give 3 examples using 3 different sources and explain the phenomenon. 

stretch an elastic band: elastic force. 

attraction of magnets: magnetism. 

hit a ball: contact.

1.  Force is a vector quantity that measures the rate of change in linear momentum between two particles or systems of particles.  2. Movement is a change in the position of a body over time with respect to a reference frame  3.    

 4. The thing that keep us stick to the ground and its called the force of gravity    

What is a force? 

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects that can affects the shape and the motion 

What is a movement? 

 Is the state of changing something's position 

What sources or types or forces are there in our environment? Mention them. 

·       Gravitational Force 

·       Normal Force 

·       Frictional Force 

·       Electromagnetic Force 

·       Air Resistance Force 

·       Nuclear Force 

When talking about forces in physics how can we analyse the phenomenon of force and movement in our environment? 

IN all, we have force, because thanks force we can be in the floor, on the earth and we can Breathe. The force are in all in the galaxy because if we don't have force the earth doesn't be in the milky way whit the sun and stars.

1.       What is a force? 

A force is push or pull one object upon other. 

2.       What is a movement? 

Movement is the action of changing the position of an object 

3.       What sources or types or forces are there in our environment? Mention them. 

Gravity, contact, magnetic, elastic and friction. 

4.       When talking about forces in physics how can we analyze the phenomenon of force and movement in our environment? 

We can see this phenomenon is us  because the forcé of attraction prevent us to float up 

5.       Give 3 examples using 3 different sources and explain the phenomenon 

Elastic: force generated by a spring 

Contact: when we pull a door 

Magnetic: when a magnet attract an object 

1.       A force is a push or a pull upon an object and an interaction between many objects. 

2.       A movement is the change of place or position of a body. 

3.       Gravity, magnetic, friction, electricity. 

4.       The force is always present in our environment, even when we don’t know we are using it. 

5.       Magnetic: when a magnet attracts an object. 

Electricity: the charge in a bulb 

Gravity: the force that stick us to the ground. 

What is a force? 

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. 

What is a movement? 

 The movement is the change of place or position or posture studying the movement of the planets. 

What sources or types or forces are there in our environment? Mention them. 

force of gravity, friction and contact. 

When talking about forces in physics how can we analyze the phenomenon of force and movement in our environment? 

Gravity: The force that attracts a body towards the centre of the earth, or towards any other physical body having mass. 

Friction: The resistance that one surface or object encounters when moving over another. 

Contact: Union of two things or people in a way that they come to touch. 

Give 3 examples using 3 different sources and explain the phenomenon. 

1)    An object thrown into the sky. A cannonball, for example, will fly in a straight line until it undergoes a loss of acceleration, the result of gravity, curving its trajectory. When it exceeds the initial force of the explosion, the object will fall and stop moving. Gravity 

2)      An ice skating rink, where friction is reduced and therefore skates are used so that the displacement is greater. Friction 

3)    Kick a ball the force we apply to it causes it to accelerate from a speed of zero to a speed of tens of kilometers per hour. When the ball is released from the foot, it begins to slow down due to the friction force exerted on it. Contact

1. What is a force? 
2. What is a movement? 
3. What sources or types or forces are there in our enviroment? Mention Them.                                                                4. When talking about forces in physics how can we analyze the phenomenon of force and movement.                      5. Give 3 examples using 3 different sources and explain the phenomenon.                                                       

 ANSWERS: 
R1/ Force is a physical phenomenon capable of modifying the speed of displacement, movement, structure, and attraction of a body, according to the point of application, direction and intensity given. FORCES AS: Push, Stretch, Launch and attraction. 

R2/ Movement is the change of position that a body experiences in space in a certain period of time. 

R3/ KINETIC FORCE: Is the energy that a body possesses because of its movement that allows an object to go from being at rest, or still, to moving at a certain speed. 
 ELASTIC FORCE: Is the force exerted on elastic objects which react against the deforming force to recover their original shape. 
APPLIED FORCE AND THRUST: It is the external force that acts directly on a body. While the thrust force is defined as the reaction force action as described in Newton's third law. 

 
R4/  The phenomenon of force can be observed by modifying the speed and movement that is given to an object depending on the intensity of force that is applied, this can be observed as it is in the case of the gravitational force of each planet in the solar system, each one has an atmosphere that exerts a force on the body that enters the atmosphere.  
EXAMPLE: Jupiter will apply greater gravitational force because it has more mass than the earth. 
Is the physical phenomenon that defines the change of position of a body in space.            
EXAMPLE: when we move a large box to another location in space. 

 
R5/ EXAMPLES: 

PHENOMENON OF FORCE 
- When the rain falls to the earth's surface. (GRAVITATORY) 
- The power that a rocket must exert to leave the planet. (GRAVITATORY) 
- The attraction of the sun with all the planets of the solar system. (GRAVITATORY) 
- The compass when pointing north. (ELECTROMAGNETIC) 
- A magnet when attracting a metal object. (ELECTROMAGNETIC) 

PHENOMENON OF MOVEMENT 
- Running alongside a moving car. 
- Dropping an object into an ascending plane.
