Newton’s Laws of Motion

• First Law of Motion– Law of Inertia– “An object will remain at rest or continue with

constant velocity unless acted on by an unbalanced force.”

– Bodies or objects stay where they are or keep moving unless acted on by an unbalanced force.

2nd Law of Motion

• Law of Acceleration• “The acceleration (for a body/object of

constant mass) is proportional to, and in the same direction as the unbalanced force applied to it.”

• F = m x a

3rd Law of Motion

• Law of Reaction• “When one body or object applies a force to

another, the second body or object will apply a force equal in size but opposite in direction to the first body or object.”

• Simply put – For every action there is an equal and opposite reaction.

Projectile MotionAny object released into the air.

Factors affecting Projectile Motion– Height of release– Angle of release– Speed of release– Air resistance– Gravity
