Can a centripetal force ever do work on an object. explain?
Centripetal force refers to the force that acts on a body moving in a circular path. It does not do work on an object because it acts perpendicular to the motion of the body. The work done on a rotating object is zero.
Why work done by centripetal force during half rotation is zero?
work done is zero because force is toward the centre and distance is tangent to the circle so cos90 is equal to zero.[abbasia]
How does the Centripetal Force work?
The Centripetal Force is the one that pulls an object that travels on a given path about a point in the direction of this point. This force has been stated by Isaac Newton.
Is centripetal force a outward force?
No; "centripetal" implies an inward force.

Is Work done by centripetal force is zero?
An object moves in a circle at constant speed. The work done by the centripetal force is zero because: 1. the displacement for each revolution is zero 2. the average force for each revolution is zero 3. there is no friction 4. the magnitude of the acceleration is zero 5. the centripetal force is perpendicular to the velocity

When is work done though displacement is zero?
When an object is propelled by a non-centripetal force through a closed path.

How does the wall of death work?
due to centripetal force
Does centripetal force do work on the particle on which it acts?
No, because the force is perpendicular to the movement.
What is the evidence for determining whether or not work is done on an object?
Basically if the energy of the object has changed. For example if you lift something off the ground you have applied a force through a distance in the same direction as the force. By lifting the box you have given it gravitational potential energy (mgh). If you drop the box then gravity does work because the force of gravity will apply a force through a distance in the same direction. Just because there is force, doesn't mean work has been done. For example if you look at uniform circle motion even though there is a force, known as centripetal force, there is no work being done. This is because centripetal force is always perpendicular to velocity and only components of force parallel to the object can do work on it. We can tell no work has been done because the kinetic energy of the object remains the same (=1/2*m*v2).

How centripetal force equals to gravitational force?
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.
