Displacement. 1. Distance is the actual length of the path travelled by the particle in a given interval of time. Displacement is the shortest distance between the initial position and the final position of the moving particle in a particular direction. 2. Distance travelled by the particle in a given interval of time is always positive. lga to ewr shuttle price

WebApr 6, 2024 · Deceleration, also known as retardation or negative Acceleration, is the Acceleration acts in the opposite direction of Motion and is responsible for reducing the … WebMar 8, 2024 · It is defined as rate of change of velocity with time. Acceleration = Change in velocity / Time taken for change. = Final velocity – Initial velocity / Time taken for change. a = (v-u)/t. S.I. unit is m/s2 or cm/s2. Acceleration is a vector quantity. If a body moves with uniform velocity its acceleration will be zero because its velocity is zero.
