Some work done by centrifugal force is present in our everyday lives. For instance, a clothes washer uses a rapidly spinning drum to sling and squeeze the water and soap out of clothes to wring them out. Another example is a carnival ride, such as one with hanging swings on it. As the ride spins faster, the swings swing outward due to centrifugal force!

Why work done by centripetal force during half rotation is zero?
The centripetal force always acts perpendicular to the displacement of the object moving in a circular path. Since the work done is the product of force and displacement in the direction of force, and the displacement is perpendicular to the centripetal force, the work done by the centripetal force over a full rotation is zero.
Can a centripetal force ever do work on an object. explain?
No, a centripetal force does not do work on an object because the force is perpendicular to the displacement of the object. Work is only done when a force applied on an object causes displacement in the direction of the 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
Why does 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
Why is the workdone by centripetal force is zero?
The work done by a centripetal force is zero because the force is always directed towards the center of the circular motion, while the displacement is perpendicular to the force. This means that the angle between the force and the displacement is 90 degrees, resulting in zero work being done.
Why does work done by centripetal force?
The centripetal force does not do work on an object because it acts perpendicular to the direction of motion. It is responsible for changing the direction of the object's velocity, keeping it moving in a curved path, but it does not change the object's kinetic energy.
When is work done though displacement is zero?
When an object is propelled by a non-centripetal force through a closed path.
Explain why a centripetal force does not do work on a circularly moving object?
A centripetal force does not do work on a circularly moving object because the force is always directed towards the center of the circle, while the object moves tangentially to the circle. Since work is defined as force acting in the direction of displacement, the centripetal force and the displacement are perpendicular to each other, resulting in no work being done.
What is the work done by a body moving along a circular path?
The work done by a body moving along a circular path is zero if the force is perpendicular to the direction of motion, such as in the case of centripetal force. This is because the displacement is perpendicular to the force. If there is a component of the force in the direction of the motion, work is done, calculated as the dot product of the force and displacement vectors.
How does the wall of death work?
due to centripetal force
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).
Does centripetal force do work on the particle on which it acts?
No, because the force is perpendicular to the movement.
