Motion, Speed, Acceleration, and Velocity Test

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

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

Acceleration only takes place when things speed up.

• true

• false
