Write the equation of friction force parallel to the surface of slope for rolling body.

How much the acceleration parallel to the surface of slope for a rolling body?

Little more for rolling body :

Write equation of Lorentz force.

Assertion: Frictional force is the component of contact force parallel to the surface. Reason: Friction force always opposes the motion of a body.

Assertion: When a force vecF attempts to slide a body along a surface, a frictional force parallel to the surface and directed so as to oppose the sliding, is exerted on the body by the surface. Reason: It is due to the bonding between the body and the surface.

What is rolling friction

A solid sphere rolls without slipping on an inclined plane of angle theta . Find its linear acceleration in the direction parallel to the surface of the inclined plane.

Write the equation of three lines that are (i) parallel to the X-axis (ii) parallel to the Y-axis

According to the equation for gravitational force, what happens to the force between two bodies if the mass of one of the bodies doubled ?

Explain why friction is necessary to make the disc in Fig. 7.41 roll in the direction indicated. (a) Give the direction of frictional force at B, and the sense of frictional torque, before perfect rolling begins. (b) What is the force of friction after perfect rolling begins ?
