Physical Science Unit 06: Motion (Chapter 04) Review

Describe the motion of the car. (Car is stopped)

• The car has acceleration because it is at rest 
• The car does not have acceleration because it is at rest 
• The car has velocity because it is at rest 
• The car has acceleration because it is at rest 

Acceleration: is the rate of change in ___________.

• speed

• distance

• velocity

• displacement

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.

• A car approaching a red light

• A car with the cruise control set at 80 km/h

• A car moving down a ramp

When are you undergoing an acceleration in a car?

• speed up

• slow down

• make turns

• All of the above

Velocity is both ____ and _____.

• speed , direction

• direction, mass

• volume, density

• direction, magnitude

A negative acceleration means that your object is _____.

• Going to Wal-mart

• running for president

• speeding up

• slowing down

A roller coaster going down a hill is changing which aspect of its movement?

• speed and acceleration

• distance and time

• speed and direction

• force and momentum

The SI unit for acceleration is

• mph

• ft/sec²

• m/s²

Determine the motion of the car.

• at rest 
• moving at constant speed
• speeding up
• slowing down
