The instantaneous speed of the point of contact during rolling is zero.

The instantaneous acceleration of the point of contact during rolling is zero.

The instantaneous speed of a body can be measured:-

The instantaneous angular position of a point on a rotating wheel is given by the equation theta_((t))=2t^(3)-6t^(2) . The torque on the wheel becomes zero at ………. s

Assertion: In general |Displacement| le distance. Reason: The instantaneous speed is equal to the magnitude of the instantaneous velocity,

The x-intercept of the tangent to a curve is equal to the ordinate of the point of contact. The equation of the curve through the point (1,1) is

The linear momentum of a particle at time t is given by the equation P = x + yt^(2) , where x and y are constants. The instantaneous force acting on the particle during its motion is .....

A wheel of 1 m radius completes half rotation on horizontal path. Magnitude of displacement form the point of contact with path initially is………

In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

Prove that perpendicular at the point of contact to the tangent to circle passes through the centre.
