Newton's 3 Laws of Motion

First Law of Motion

Law of 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

Example

In bowling, the pins are at rest. They will remain that way until an external force (a 15 pound ball hurling down a lane) causes them to move

Second Law of Motion

Name

Force= Mass x 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).

Example

Your friend is on a skateboard. You push him forward, and he moves. A little push, and he begins to move slowly. A big push, and he moves faster, and gains speed more quickly., New node

Third Law of Motion

Name

Action + Reaction

Definition

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

Example

When you do a cannon ball into a pool, you strike the water with some force and the water exerts an equal and opposite force on you
