EVERYDAY SCIENCE

Detailed explanation-1: -acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.

Detailed explanation-2: -The rate of change of velocity is called acceleration. Acceleration is the ratio of change in velocity with time. The SI unit of acceleration is m/s2.

Detailed explanation-3: -Hence, the rate of change in velocity is called acceleration.

Detailed explanation-4: -In physics, jerk or jolt is the rate at which an object’s acceleration changes with respect to time. It is a vector quantity (having both magnitude and direction).
