Inertia

Newton's first law is also called the Law of ...

• Friction

• Inertia

• Unbalanced forces

• Newtons

An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is an example of Newton's

• Second Law

• First Law

• Third Law

If an object is stationary, it means

• the object is in motion

• the object is not in motion

• the object is experiencing air resistance

• there are unbalanced forces acting on the object

If an object is stationary, it means

• the object is in motion

• the object is experiencing air resistance

• there are balanced forces acting on the object

• there are unbalanced forces acting on the object

The tendency of an object to resist a change in its motion is called

• inertia

• friction

• tension

• gravity

Without an unbalanced force, a moving object will not only keep moving, but its ______________________________ will also remain the same.

• force and motion

• speed and time

• speed and direction

• inertia and distance

Which statement explains why you are thrown forward when the car you are riding in suddenly stops?

• You are pushed forward by the force of the car stopping

• The force of the crash accelerates you forward

• You are are in motion as the car is driving, and when it stops, your body continues to be in motion

• The car stopping must balance out by having you move forward
