Speed, Velocity, and Acceleration Quiz from STEAMspirations vide

What is speed?

• A measure of how fast an object is moving

• A rate of change of an object's velocity

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

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

What is velocity?

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

• A measure of how fast an object is moving

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

• A rate of change of an object's velocity

What is acceleration?

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

• A rate of change of an object's velocity

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

• A measure of how fast an object is moving

Which of the following is a scalar quantity?

• Velocity

• Acceleration

• Distance

• Speed

Which of the following is a vector quantity?

• Velocity

• Speed

• Acceleration

• Distance

How is velocity different from speed?

• Velocity has both magnitude and direction, while speed only has magnitude

• Velocity has only magnitude, while speed has both magnitude and direction

• Velocity is a measure of how quickly an object's velocity is changing, while speed is a measure of how fast an object is moving

• Velocity is a rate of change of an object's velocity, while speed is a measure of how fast an object is moving

How is acceleration measured?

• Miles per hour

• Meters per second squared

• Meters per second

• Kilometers per hour

What happens when an object accelerates?

• Its speed changes

• Neither its speed nor direction of motion change

• Its direction of motion changes

• Both its speed and direction of motion change

Can an object have a constant speed but changing velocity?

• Yes

• No

How can acceleration change?

• Neither by changing speed nor changing direction of motion

• Both by changing speed and changing direction of motion

• By changing speed

• By changing direction of motion
