What is the work done on the body in one revolution?

Constant speed means no acceleration hence no force applied, the mass has some energy stored but neither increassing nor decreassing so the work done on it is zero.

What is the work done by centripetal force during one revolution?

How much work is done by the centripetal force during one-half of a revolution? Since the centripetal force always points along a radius toward the center of the circle, and the velocity of the object is always tangent to the circle (and thus perpendicular to the radius), the work done by the centripetal force is zero.

What is the work done during the motion of an object?

Work done on an object along a given direction of motion is equal to the force times the displacement times the cosine of the angle. No work is done along a direction of motion if the force is perpendicular.

What is the total work done on the object?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).

Is work done in a circle?

Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules. Recall also from Unit 5 of The Physics Classroom that when no work is done upon an object by external forces, the total mechanical energy (potential energy plus kinetic energy) of the object remains constant.

What is the work centripetal force?

The direction of centripetal force is always perpendicular to the direction of instantaneous velocity. The instantaneous displacement is in the direction of instantaneous velocity, therefore instantaneous displacement of particle is perpendicular to centripetal force. Hence work done by centripetal force is zero.

How do you find the work done on an object?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

Why is the work done on an object moving with uniform?

Work done on an object is the force applied and the displacement covered in the direction of the force applied. W=FScosθ. Force in uniform circular motion is always perpendicular to the displacement and hence the angle between F and S is 900 always. Hence, The work done in a uniform circular motion is always zero.
