What is the difference between muscular force and rolling force?Give t...
Muscular force is the force applied using parts of the body like arms or legs. It is force that results due to the action of muscles, and is a contact force, since there is a contact between the surfaces. Muscular force is needed whenever movement of the body occurs.
Some Examples of muscular force are:
1. Kicking a ball, while kicking a ball we touch the ball with our legs and apply the force on ball to make it move.
2. Lifting a wieght , while Lifting wieghs we make contact with the surface of wieght and apply muscular force on it like to lift it.
3. Walking , running, jumping etc. all are examples of muscular force and there are many more activities which are done by applying power of muscles that all will be example of muscular force.
Rolling friction:
When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction.
So, Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface.
The actual rolling friction can be measured and expressed as a number multiplied by the normal force.
It is always easier to roll than to slide an object over another object. So rolling friction is much less than the sliding friction.
Cause of rolling friction:
When an object is rolled on a surface, certain things happen:
1. The object is deformed at the point of contact with the surface.
2. The surface is deformed at the point of contact with the object.
3. Motion is created below the surface as a result of the above mentioned points.
Examples of rolling friction in everyday life
1. A basketball rolled on the court will eventually come to a halt because of rolling friction.
2. A bike with a broad tire will burn more fuel because of the increased rolling friction.
3. A ball rolled on a field will go lesser distance than a ball rolled on a concrete floor because it will experience greater rolling friction on the former surface.
