U1L2 Acceleration

Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft

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

Acceleration only takes place when things speed up. 

• True
• False

In which situation is no acceleration taking place.

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed

Acceleration can be classified as _______________

• Speeding up
• Slowing Down
• Changing directions
• All of the above
