A CAR TRAVELS AROUND A RACETRACK AT A CONSTANT SPEED. DURING WHAT PARTS OF THE COURSE DOES THE CAR EXPERIENCE ACCELERATION?

Sep 18th, 2014

The car would experience acceleration whenever the direction changes because acceleration refers to the change in velocity which is a vector of speed and direction. So, whenever the car is turning it would experience acceleration. If we are assuming an oval racetrack it would accelerate around the end of the track where it is round and the velocity would be constant on the straights of the track.
