Speed and Acceleration Review Game

When an object’s distance from another object is changing,

• it is in motion.

• it is speeding.

• it is accelerating.

• it is moving at a high velocity.

Speed equals distance divided by

• time

• velocity

• size

• motion

When you know both the speed and direction of an object's motion, you know the

• average speed of the object

• acceleration of the object

• distance the object has traveled

• velocity of the object

The rate at which velocity changes is called

• speed
• direction
• acceleration
• motion

Which of these is an example of negative acceleration (or deceleration)?

• a bird taking off for flight

• a baseball released by a pitcher

• a car approaching a red light

• an airplane following a straight flight path

A place or object used for comparison to determine if something is in motion is called 

• a position
• a reference point
• a constant
• velocity

Changing direction is an example of a kind of

• acceleration

• speed

• velocity

• constant rate

If a bicyclist travels 30 km in 2 hours, her average speed is

• 30 km/h

• 60 km/h

• 15 km/h

• 2 km/h

The moon accelerates because it is

• in a vacuum in space.
• continuously changing direction.
• a very large sphere.
• constantly increasing its speed of orbit.
