Question

define acceleration??????​

Answer 1

Answer:

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.

Answer 2

Measure of how fast velocity is changing, so we can think of it as a change in velocity overtime. The most common use of acceleration is acceleration due to gravity which can also appear as gravitational constant (9.8 m/s2)
