A car of mass m travels at constant speed v around a circular track of radius r. What is the magnitude of the centripetal force acting on the car?
A.C) mv/r²
B.A) mv²/r
C.D) mrv²
D.B) mvr
Explanation
Core Concept
The centripetal force required for circular motion is given by F = mv²/r. This force is directed toward the center of the circular path and is necessary to change the direction of the velocity vector.
Correct Answer
BA) mv²/r
