Second Law of Motion - The unbalanced force acted on an object equals to the product of its mass and its acceleration.
F = ma 

Third Law of Motion -  Every action has an opposite and equal reaction.]]> 2016-05-23 06:56:05 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112066043 gam0008 https://padlet.com/gam0008/ff7n3cgevema/wish/112066120 First Law of motion -  An object at rest, stays at rest or an object in motion stays in the same velocity and in the same direction unless acted upon by an unbalanced force. 

Velocity is the speed of an object in a specified direction. An unbalanced force is an external force that changes the motion of an object. When an object is at rest or moving at a constant velocity, all the forces acting on it are balanced.

If a force doesn't apply on an object the object will remain at rest. Even you kicked a stone, it won't move if the forces act on are balanced. If the stone is moving in an equal velocity we can say that its forces are balanced. If you want to stop the stone you should apply an unbalanced force on it.]]> 2016-05-24 10:06:32 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112292392 https://padlet.com/gam0008/ff7n3cgevema/wish/112296829  The netforce equals the to the product of mass and its acceleration. Acceleration is produced when an unbalanced  force acts on a mass. The greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object.

If you try to push a stone which is 100kg it will not move. If a stronger person or an animal like an elephant can moved it, it would move because the stronger animal or the person exerts a large force as well as stronger acceleration.]]> 2016-05-24 10:59:53 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112298950 gam0008 https://padlet.com/gam0008/ff7n3cgevema/wish/112299726 Third Law of Motion states that for every action has an opposite and equal reaction.]]> 2016-05-24 11:07:47 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112299726 gam0008 https://padlet.com/gam0008/ff7n3cgevema/wish/112300659 In this video it teaches us that  every action has an opposite and equal reaction. If you sit on a chair our body exerts a downward force on the chair. The chair also exerts an upward force. If it doesn't we will collapse. ]]> 2016-05-24 11:16:24 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112300659 gam0008 https://padlet.com/gam0008/ff7n3cgevema/wish/112449325 A football is remaining at rest in the first diagram.
The football is moving at the  same velocity in the second diagram. The moving ball can be stopped by giving an unbalanced force in the last diagram.]]> 2016-05-25 04:06:56 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112449325 gam0008 https://padlet.com/gam0008/ff7n3cgevema/wish/112449718 This picture demonstrates that the man has a less force than the elephant. With the formula [Mass into acceleration = Force] I calculated the Force. Assume the man has the net force of 10N and the elephant has the net force of 100N. The force of the elephant is 10 times stronger than the force of the human. So the man can produce  less acceleration on the stone while the elephant can produce a large amount of acceleration to the same object.]]> 2016-05-25 04:13:00 UTC https://padlet.com/gam0008/ff7n3cgevema/wish/112449718 gam0008 https://padlet.com/gam0008/ff7n3cgevema/wish/112450838 To fly free in the air the bird should flap its wings. When it flaps it's wings downwards, it pushes the air downward. Then the air pushes the bird up to the sky.
