How many laws of motion are there said to be?

• 1

• 2

• 3

• 4

Identify Newton's 1st Law of Motion

• Every object stays at rest unless acted on by an outside force

• The acceleration of an object depends on its mass and force acting on it

• For every action, there is an equal and opposite reaction

Identify Newton's 2nd Law of Motion

• For every action there is an equal and opposite reaction

• The acceleration of an object is measured by its mass and the force acting on it

• Every object stays at rest unless acted upon by an outside force.

Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

• True

• False
