Motion and Speed

What is the formula to calculate speed?

• Speed = time / distance

• Speed = distance x time

• Speed = distance / time

• Speed = time x distance

What is speed?

• The rate at which an object moves by comparing the distance traveled by the amount of time it takes.

• How far you go.

• How fast you accelerate

• The rate at which the velocity changes over a given amount of time.
