Give an example of negative acceleration from daily life situation. |
|
Answer» Negative acceleration is nothing but retardation. Acceleration is rate of change of velocity. But negative acceleration means that the rate of change of velocity is negative or velocity decreases. Example: (1) When we apply brakes in a moving car, then negative acceleration acts on it and the car stops. (2) When we throw a ball upwards, then also negative acceleration acts on it. Thus, when the ball reaches the highest point, velocity of the ball becomes zero. |
