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.
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 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.
What is the connection between conservation of energy and centripetal force?
The conservation of energy principle states that the total energy of a system remains constant if no external forces act on it. In the case of circular motion, centripetal force provides the necessary inward acceleration to keep an object moving in a circular path. The work done by this force is supplied by the object's kinetic and potential energy, demonstrating the connection between conservation of energy and centripetal force.
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.
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

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

How much work is done by the centripetal force on a body along a circular path?
Zero. W = F* d cos (Theta) W = Tension * displacement * cos (90) The force is perpendicular to the objects motion (or displacement of the object) W = T * d * 0 W= 0
How is artificial gravity provided by the centripetal force?
In science-fiction novels, large wheels are set up in space. It is very likely that this will eventually be done seriously. Somebody on the rim of such a large wheel would be accelerated towards the center of the wheel; the acceleration has a magnitude of v2/r. The person or object would feel this as a centrifugal force - a ficticious force. On a small scale, this force has just the same effect as gravitation.
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.
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).
