• ramps

• Sideways acceleration

• Rocket engines

Acceleration occurs whenever there is a change in:

• Either speed or direction

• Neither speed nor direction

• Direction

• Speed

At constant speed in a straight line, the acceleration is:

• positive

• It can be any of these

• negative

• zero

Speed with direction is:

• velocity

• position

• vector

• time

The direction of the acceleration of an object in circular motion stays pointed:

• Away from the center of the circle

• Toward the center of the circle

• Up

• Down

The distance divided by the time is the:

• position

• acceleration

• speed

• vector

What is acceleration?

• Change in position multiplied by the change in time

• Change in position divided by the change in time

• Change in velocity multiplied by the change in time

• Change in velocity divided by the change in time

Which is NOT a common unit for speed?

• Meters per second

• Kilograms per second

• Centimeters per second

• Miles per hour

A newton is a little less than

• ½ pound

• ¼ pound

• ⅛ pound

• 1 pound

If the net force doubles, the acceleration:

• Is cut in half

• doubles

• Stays the same

• Quadruples
