Is the car accelerating? If you set the cruise control of your car to a certain speed and take a turn, the speed of the car will remain the same.
yes or no?
The acceleration of a body is defined is the change in velocity of the body. Speed is a scalar while displacement is a vector implying that the magnitude as well as the direction are relevant.
If a car 's controls are set to ensure a constant speed and it takes a turn the car is accelerating as the initial velocity and final velocity are not the same in direction though the magnitude (which is the speed) is constant.
The car turning at a constant speed is accelerating.
