Speed, Velocity, and Acceleration Review

What is speed?

• A measure of how fast an object is moving

• A measure of both the speed and direction of an object's motion

• A rate of change of an object's velocity

• A measure of how quickly an object's velocity is changing

What is velocity?

• A measure of how fast an object is moving

• A measure of both the speed and direction of an object's motion

• A rate of change of an object's velocity

• A measure of how quickly an object's velocity is changing

What is acceleration?

• A measure of how fast an object is moving

• A measure of both the speed and direction of an object's motion

• A rate of change of an object's velocity

• A measure of how quickly an object's velocity is changing

Which of the following is a scalar quantity?

• Speed

• Velocity

• Acceleration

• Distance

Which of the following is a vector quantity?

• Speed

• Velocity

• Acceleration

• Distance

How is acceleration measured?

• Meters per second

• Meters per second squared

• Miles per hour

• Kilometers per hour

Can an object have a constant speed but changing velocity?

• Yes

• No

What causes a change in acceleration?

• A change in speed

• A change in direction

• Both a change in speed and a change in direction

• Neither a change in speed nor a change in direction
