Question

Among static sliding and rolling friction which is more and why

Answer 1

Sliding friction is more than rolling friction because The frictional force present when one object moves slowly or slides over the surface of another object is known as sliding friction whereas When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction.

Answer 2

Answer:

Explanation:

When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases.

As the object touches the ground, all its potential energy gets converted into kinetic energy.

As the object hits the hard ground, all its kinetic energy gets converted into heat energy and sound energy.

It can also deform the ground depending upon the nature of the ground and the amount of kinetic energy possessed by the object.
