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

What is occurring from point A to point B?

• they are traveling at a constant speed

• they are decreasing in speed

• they stopped to take a break
