GENERAL KNOWLEDGE

Detailed explanation-1: -In fact, a car accelerates whenever its velocity is changed by either changing the speed or the direction of the car’s motion. So, even if you are driving your car at a constant speed while turning around a corner, you are still accelerating.

Detailed explanation-2: -For example, if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration. So there is an acceleration when velocity changes either in magnitude (an increase or decrease in speed) or in direction, or both.

Detailed explanation-3: -The correct option is D An object moving with a constant velocity.

Detailed explanation-4: -Acceleration is a measure of the change in velocity of a moving object. It measures the rate at which velocity changes. Examples of acceleration include driving at a constant speed around a bend in a road and riding on a carousel.
