newton's law
Storyboard Text
- The amount of acceleration of a body is proportional to the acting force and inversely proportional to the mass of the body
- For every action force there is an equal but opposite reaction
- Everybody remains in a state of rest or uniform motion unless acted upon by a net external force
- 3rd newton law
- 2nd newton law
- 1st newton law
- examplewhen you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force
- examplePushing a cart. It is easier to push an empty cart in a supermarket than a loaded one, and more mass requires more acceleration.
- examplea ball is on a the ground and someone comes and kicks the ball
- newton's first lawthe ball will stay still unless another force comes and gives it motion
- If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.
- Sir Isaac Newton was sitting under an apple tree pondering as to why things always fell to the ground… And then it hit him.
