What is velocity?

• the quickness of an object

• the location of an object

• acceleration

• speed in a specific direction

Does the speedometer of a car read average speed or instantaneous speed?

• average speed

• instantaneous speed

In the absence of air resistance, objects fall at constant

• velocity.

• acceleration

• speed

• distances each second
