Speed, Velocity, and Acceleration Vocabulary

What is velocity?

• the quickness of an object

• the location of an object

• acceleration

• speed in a specific direction

The tornado is traveling northwest at 20 mph. 

• speed

• velocity

• acceleration

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant

• The car accelerates because it's going 20 mph

• Cars always accelerate when they are in motion

• The car is accelerating because it's changing direction

Which of the following statements about speed and velocity is correct?

• Velocity only describes an object’s rate of motion.

• Speed describes how an object is changing its velocity.

• Speed and velocity both describe how an object is speeding up.

• Only velocity includes the direction an object is traveling.
