What is Newton's first law state?
That anything at rest cant be moved unless a force is acted upon it
anything in motion can't be stopped unless friction or another force is acted on it to stop
Anything at rest can be moved without a force acted on it
What does Newton's second law state?
That if an action is acted upon an object their will be a reaction from the other object.
That an object at rest wont move unless a force is acted on it.
That the net force acting upon an object depends on the mass of an object.
Whats Newton's third law state?
A force does not have to be acted upon a object for the object to move.
Any action that is acted upon an object states that the other object will have a reaction.
A force must be acted on a object for the object to move.

Say you were riding your skateboard, and you accidentally hit a rock. What would happen, and which law would that be?
Second law, the board will keep moving and your body will stop.

third law, the board will stop and so will you.
Say you were to push your dad, which law would that be and why?
Third law, He will move back then you will because every action has a reaction.
First law, he will move back because of the force you put on him.
Second law, Because of your dads mass (which is larger than yours) he wont accelerate like most things because you won't have enough force.
What causes a rocket to shoot up in the air?
Newton's third law, the rocket would push out fire with an amount of force and the rocket will shoot up with the same amount of force.
Newton's first law, the rocket wont move unless a force from someone is acted upon it.
Newton's second law, the force from someone will be enough for the rocket to accelerate into the air.

F=MxA
F=A/M

Is it easier to kick a beach balls or a bowling ball? why?
beach ball because The second law states that it is easier to apply a force to an abject with less mass.
bowling ball because Newtons first law states that if you apply a force it will move and the bowling ball is smaller.
What is an example of the second law.
a magician pulling a tablecloth from under utensils and plates and nothing but the table cloth moving.
kicking a beach ball rather then a baseball because it has less mass.
throwing a ball at the wall and it coming back and hitting you in the face.
