Speed, Velocity, and Acceleration Wrap-up

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

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

How can acceleration change?

• By changing speed

• By changing direction

• Both by changing speed and changing direction

• Neither by changing speed nor changing direction
