Motion Forces

The unbalanced force that opposes motion is known as...

• friction

• force

• push or pull

• the tires on a car

Forces that are considered to be in motion are called...

• friction

• unbalanced forces

• balanced forces

• A larger car because of its mass

• A smaller car because of its mass

• A larger car because of its speed

• A smaller car because of its speed

Why does a person continue to fly forward in a car after a crash?

• the person is not moving until the car stops

• the person jumps out of the car

• the person has more force than the wall

• the person is still in motion

Inertia is...

• an objects ability to change direction

• an objects ability to move

• forces depend on the mass and weight of the object

• an objects tendency to resist change in motion
