Question

what is acceleration​

Answer 1

Answer:

Acceleration is the measurement of change in an object's velocity. ... This change in velocity is acceleration. The equation for calculating acceleration is: Acceleration = (change in velocity)/(change in time) or a = Δv ÷ Δt . The standard unit of measurement for acceleration is meters per second squared or m/s2.

Answer 2

Step-by-step explanation:

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
