When a car driver travels at a constant speed and turns a corner on a flat road, what happens to the velocity of the car?
- A.Velocity remains constant because speed is constant.
- B.Velocity changes because the direction of motion changes.Correct answer
- C.Velocity becomes zero.
- D.Velocity increases continuously.
Solution
Velocity is a vector quantity that depends on both magnitude (speed) and direction. When a car turns a corner, its direction changes, and therefore its velocity changes even if its speed remains constant.
