Acceleration Exit Ticket

Acceleration is

• the rate at which velocity changes.

• the change in velocity

• the rate of change

• when you speed up only

Velocity has two components

(pick 2 below)

• direction

• change in speed

• speed up

• slow down

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

Which of the following is a unit for acceleration?

• km/s
• m/s²
• mi/hr
• ft

Which is acceleration?

• Speeding up

• Slowing Down

• Changing Direction

• All of these answers are correct
