Positive acceleration is an object:

• moving forward.

• moving backwards

• increasing in velocity

• decreasing in velocity

Negative acceleration is an object that is:

• decreasing velocity

• increasing velocity

• moving backwards

• moving forwards

Negative acceleration is also called:

• deceleration

• kinetics

• mechanics

• positive uniform acceleration

Constant acceleration is also called:

• constant velocity

• uniform velocity

• constant speed

• uniform acceleration

An object traveling at constant velocity:

• travels at the same velocity for a designated time

• travels at an increasing velocity for a designated time.

• travels at a decreasing velocity for a designated time.

An object traveling at a constant acceleration:

• travels at the same velocity.

• travels at an regularly increasing or decreasing velocity

• has an initial velocity of zero

• has a final velocity of zero

Acceleration occurs even when the speed stays the same and only the direction changes.

• True

• False

An object with a positive constant acceleration could have a velocity that is:

• constantly changing each second therefore it gets faster and faster.

• constantly changing each second therefore it gets faster and then slower.

• constantly changing each second therefore it gets slower and then faster.

• constantly changing each second therefore it gets slower and slower.
