# newtons 3 laws#1 inertia

newtons 1st law means that something will stay in rest unless a force acts on it. Also something will stay in motion unless a force acts on it.

this picture shows that this object was in motion but a unbalanced force stopped the car from being in motion.

I could show the class a car rolling down a hill with a force stopping it

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Acceleration is produced when a 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).

the second law means that how heavy or light the object is depends on how much force is used to move it.

the picture shows that the man has to apply alot of force so he can push a heavy object

a demonstration is that i could push something showing that i dont have to apply alot of force to push it

For every action there is an equal and opposite re-action.

when there is a action there has to be the same or different reaction that happens because of the action

this picture shows that when the cars crashed that was a action and when the cars bounced off of each other that was the reaction that happened because of that action

a demonstration is that i could slap my hand and that would be the action and that reaction would be the noise my hands made because of the reaction.
