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

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

• A car speeds up after a stoplight turns green.

• A car slows down as it approaches a red light

• A car with the cruise control set at 80 km/h going down a straight highway

• A car turning a curve at a constant speed

When are you undergoing an acceleration in a car? (Choose all that are correct)

• speed up

• slow down

• make turns

• constant speed

The graph shows

• positive velocity that's getting faster

• negative velocity that's getting faster

• negative velocity that's getting slower

• positive velocity that's getting slower

The graph shows
