Acceleration Flashcards

All 4 cards in this deck

What is the equation that relates acceleration to change in velocity and time taken?

acceleration = change in velocity ÷ time taken, i.e. $a = (v - u) \div t$, in m/s².

What is the value of the acceleration in free fall, g?

10 m/s².

True or false? An object falling at a constant velocity has zero acceleration.

True. Its velocity is not changing, so the acceleration is zero.

What is deceleration?

Negative acceleration: the velocity is decreasing. e.g. a deceleration of 3 m/s² is an acceleration of −3 m/s².
