Question

What is Acceleration ??​

Answer 1

Answer:

A small body starts sliding down an inclined plane of inclination theta whose base length is equal to l . the coefficient of friction between the body and the surface is 'u'. if the angle theta is varied keeping 'l 'constant at what angle will the time of sliding be least

Answer 2

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
