Newton's Laws Test Review

Force is...

• an invisible force that attracts and pulls objects towards each other

• a push or pull on an object that can cause a change in motion

• an object's tendency to do nothing or stay the same

• an object's resistance to motion; usually involves objects rubbing together

Friction is...

• an invisible force that attracts and pulls objects towards each other

• a push or pull on an object that can cause a change in motion

• an object's tendency to do nothing or stay the same

• an object's resistance to motion; usually involves objects rubbing together

Gravity is...

Inertia is...

• an invisible force that attracts and pulls objects towards each other

• a push or pull on an object that can cause a change in motion

• an object's tendency to do nothing or stay the same

• an object's resistance to motion; usually involves objects rubbing together

An object in motion will stay in motion and an object at rest will stay at rest, unless acted upon by an outside force. This law is also known as the law of inertia.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Force = mass times acceleration. Example: An object with a larger mass will take more force to accelerate than a smaller object.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law
