Acceleration

An object that has 0 acceleration will NEVER be in motion.

• True

• False

An object is moving with a velocity in the positive direction. If the object experiences an acceleration opposite the direction of its motion, it would be a ________________ acceleration.

A change in direction without a change in speed is called velocity.

• True

• False

How will a skydiver's velocity change when a parachute first opens?

• The speed will suddenly decrease.

• The acceleration will suddenly increase.

• The acceleration will stay the same.

• The speed will not change.

Acceleration can never be negative.

• True

• False

____________ is the rate at which velocity changes.

_______________ is the measure of change in velocity of a moving object.

Acceleration always refers to a(n)

• change in velocity

• change in speed

• increase in speed

• change in direction

Acceleration is a vector.

• True

• False

Acceleration is defined as the CHANGE in 

• time it takes for one place to move to another place. 
• velocity of an object.
• distance divided by the time interval 
• velocity divided by the time interval
