Module 2 Review

Check all of the variables you need to find speed.

• acceleration

• distance

• time

• force

An object at rest has a velocity of

• 9.8 m/s

• 0 m/s

• 100 m/s

What is the difference between speed and velocity?

• Speed includes density

• Velocity includes density

• Speed includes direction

• Velocity includes direction

On a velocity-time graph, a negative slope means

• the object has constant speed

• the object has stopped

• the object is speeding up

• the object is slowing down

A distance time graph shows what

• acceleration

• speed

• velocity

• deceleration

Acceleration is the rate of change in ___________

• velocity

• speed

• time

Displacement includes what?

• distance

• direction

• motion

• speed

When an object covers an equal distance in an equal amount of time, it is called

• constant speed

• directional speed

• final speed

• equal speed

The unit for acceleration is

• m/s

• m

• N

• m/s^2

An object is moving if its position changes against a stationary background called:

• object point

• reference point

• deceleration point

• velocity point
