In each of the following cases, determine where the car has no acceleration ?

• 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

Why does a car accelerate as it round a corner at a constant speed?

• Its direction changes
• It doesn't
• It slows down
• Its speeds up  

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 two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

What is the formula to calculate speed?

• Speed = time/distance
• Speed = distance/time
• Speed = distance x time
• Speed = time x distance

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object
