• velocity

• speed

• acceleration

• velocity and acceleration

You travel by bus from Indianapolis, IN to Chicago, IL; the distance is 210 miles and the trip takes 3.1 hours.

What is the average speed of the bus (round to nearest whole number)?

Use [speed = distance / time]

Which of the following is accelerating?

• A girl sliding down a water slide faster and faster

• A car that stopped at a parking

• A bowling ball at rest on a rack

• A train moving in a straight line with a constant speed

A truck is traveling at a constant velocity. A car is changing its speed and direction while traveling.

Which graph explains the movement of the truck and the car?

• Graph B represents the truck and Graph A represents the car.

• Graph A represents the truck and Graph B represents the car.

• Graph A and B represents the truck

• Graph A and B represents the car

Which of these examples would have the greatest acceleration?

Note: acceleration = V2 - V1 / t then compare

• A car going from 0 mph to 60 mph in 10 seconds.

• A car going from 0 mph to 80 miles per hour in 20 seconds.

• A car going from 0 mph to 60 miles per hour in 20 seconds.

• A car going from 0 mph to 100 miles per hour in 12 seconds.
