Question

What is mean by acceleration

Answer 1

ACCELERATION:

It is defined as the rate of change if velocity.

Acceleration symbol = a.

a=change in velocity/time interval.

It is a vector quality.

SI unit = m/s square.

Dimensional formula = L/T square.

a=v-u/t.

It is of 4 types:

Uniform acceleration.
Non uniform or variable acceleration.
Acceleration due to gravity(g).
Retardation or deceleration.

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. ... Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.
