1. 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.

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
