This diagram can be used to indicate which of the following? (TWO correct answers)

• An object at rest

• An object accelerating

• An object decelerating

• an object moving at a constant velocity (speed)

• (Trick question -- there is only one correct answer)

What is the formula for speed?

• speed = distance x time

• speed=distance / time

• speed = time / distance

• speed = distance + time
