SPEED AND VELOCITY

Motion- Speed and Velocity

Multiple Choice

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

Multiple Choice

What is the formula to calculate speed?

• S = t/d

• S = d/t

• S = d x t

• S = t x d
