Question

A car is travelling around a circular track at a steady speed. A force causes it to follow the track.

What is the angle between this force and the car's velocity? Draw a diagram to illustrate your answer​.

Answer 1

The force that keeps the car moving in a circle is perpendicular to the car's velocity. The force points toward the center of the circle. The angle is 90°.
