Speed in a given direction is_________________ .

• distance
• acceleration
• time
• velocity

____________________is a measure of change in velocity during a period of time

• Deceleration
• Acceleration
• Speed
• Inertia

A change in position is called.__________________

• displacement

• shift
• relocation

Which equation could be used to solve for the average speed of a car that travels 90 m in 20 seconds?

• speed = 90 m * 20 s
• speed = 90 m - 20 s
• speed = 90 m + 20 s
• speed = 90 m / 20 s

Which factor is NOT needed to calculate a moving object’s average speed?

• total time

• total distance

• total displacement

An arrow representing velocity shows

• The distance and time of the velocity
• The color and shape of the velocity
• Speed and Direction

• The temperature and pressure of the velocity

When an object accelerates in the same direction as its motion, it has ____________ acceleration, and it______________.

• negative, slows down
• zero, maintains constant speed
• random, changes direction
• positive, speeds up
