WebNon-Uniform Speed: When a body covers unequal distances in equal intervals of time, then that body is said to be in non uniform speed. For e.g., an object thrown into air, like stone, moves at non-uniform speed, lift used to go up or down in a building. Non-Uniform Velocity: When the velocity is not uniform i.e. not constant.This implies that the velocity of the … WebRetardation is merely a negative acceleration. The body's velocity can either increase or decrease. The change in velocity is referred to as acceleration. Positive acceleration occurs when the body's velocity increases. Similarly, as velocity decreases, the acceleration … What is the retardation. Login. Study Materials. NCERT Solutions. NCERT …

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. WebAcceleration. Acceleration is defined as the rate of change of velocity with time. It is a vector quantity. Its unit is m/s 2 . Constant speed does not guarantee that acceleration is zero. For example a body moving with constant speed in a circle changes its velocity every instant and hence its acceleration is not equal to zero. lock box for building
