To understand the given situation, let us first understand the motion of a vehicle on a curved track. Fig.1 shows a vehicle of mass m traveling with a speed v on a circular track of mean radius R. As we know, for any object to move on a circular track, a force is required to act on it, directed towards the centre of the circular track (centripetal force). The magnitude of this force must be at least equal to mv^2/R. From where does this force come for motion of the vehicle on the circular track? Answer is - from friction between the tires and the track as explained hereunder.

To understand better, let us look at fig.2, which gives a view of the vehicle as seen from the ...

  • Velocity of Circular Motion

    In physics, circular motion is rotation with constant speed around in a circle: a circular path or a circular orbit. It is one of the simplest cases of accelerated motion.

  • acceleration and velocity of the circular motion

    126732 Circular Motion In uniform circular motion, the acceleration is perpendicular to the velocity at every instant. Is this true when the motion is not uniform, that is, when the speed is not constant?

  • Detailed Explanation to Circular motion

    The net force acting on an object in circular motion is always perpendicular to the direction of motion and in the direct of the center of rotation (definition).

  • Centripetal Acceleration
