Acceleration Flashcards

All 4 cards in this deck

What is acceleration?

The rate of change of velocity, i.e. how quickly an object's velocity changes. Its unit is m/s².

What is the acceleration of an object travelling at constant velocity?

Zero.

What is the value of the acceleration in free fall, g, near the Earth's surface?

10 m/s².

What is a deceleration?

An acceleration with a negative value: the object is slowing down, so its change in velocity is negative.
