Retardation: The rate of change of velocity with the time of a moving body can either be positive or negative. If the rate of change…

Uniform acceleration: If the acceleration always remains constant, then that acceleration is called uniform acceleration. The acceleration of a freely falling body due to the…

Variable acceleration: When the acceleration of a body changes with time, the acceleration is called variable acceleration. Variable acceleration can be produced due to the…
