Quiz - Laws of motion

Newton's First Law States........

• Objects at rest tend to stay at rest unless acted on by an outside force.

• Objects accelerate often and it is difficult to know when or how they will accelerate.

• Objects in motion tend to stay in motion unless acted on by an outside force.

• Both A & C

What is inertia?

• An object that is accelerating

• Gravitational force

• An objects tendency to stay at rest or in motion

• An unbalanced force

Inertia depends on __________.

• Weight

• none of these

• Mass

• Acceleration

What formula is used to calculate force?

• Acceleration = Force x Mass

• Force = Mass x Acceleration

• Work = Force x Distance

• Mass = Force + Acceleration

• None of these choices

• For each action there is an equal and opposite reaction.

• For each action there is a smaller reaction associated with it.
