Newton's Laws Review

What is Newton's 1st Law of Motion?

• An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force

• The force exerted on an object is determined by multiplying the objects mass by its acceleration

• Every action has an equal and opposite reaction

• Gravity acts on all objects with a force on 9.8 N

What is Newton's 2nd Law of Motion?

• An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force

• The force exerted on an object is determined by multiplying the objects mass by its acceleration

• Every action has an equal and opposite reaction

• Gravity acts on all objects with a force on 9.8 N

What is Newton's 3rd Law of Motion?

• An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force

• The force exerted on an object is determined by multiplying the objects mass by its acceleration

• Every action has an equal and opposite reaction

• Gravity acts on all objects with a force on 9.8 N
