Newtons Laws of Motion

Newtons First Law of Motion: Inertia

Definition: 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.

My Definition: Newtons first law states that any object in motion ill remain in motion unless a force acts against it and any object at rest will stay at rest unless a force acts against it.

This cup will not move unless a force is applied to move it. This is an example because it demonstrates newtons second law.

Demonstration: A book sitting on the table and a person pushes it off, onto the floor.

Newtons Second Law of Motion: Acceleration

Definition: 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).

My Definition: the mass of an object affects the acceleration. the greater the mass the more force is needed to be applied to the object.

this is an example of the second law because a force is being applied to the object and a greater force is needed because the object has lots of mass.

Demonstration: a person throws a baseball. they throw a bowling ball with the same force they used to throw the baseball and the bowling ball doesn't go as far.

Newtons Law of Motion: Action and Reaction

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

My Definition: every action applied to an object there is an equal and opposite reaction.

This applies to the third law because a force is applied to the ball and the ball moves. an action is applied to the ball to make it move.

Demonstration: a person applies a force and the object moves
