Question

Two cars are traveling at the same constant speed v. Car a is moving along a straight section of the road, while b is rounding a circular turn. Which statement is true about the acceleration of the cars?.

Answer 1

Car A (on a straight path) is not accelerating since velocity remains constant (speed and direction)
Car B is in constant acceleration even though velocity value remains constant (speed) velocity is a vector quantity (meaning has direction) direction is constantly changing to remain on a circular path meaning velocity is constantly changing so is acceleration!

Hope this helps :)
