When a body moves in a circular path how much work is done for I complete rotation II for half rotation?

So, the work done by the object in circular path is zero.

Is there any work done on a body in uniform circular motion?

The displacement s acts along the tangent. Thus, the angle between force F and displacement s is 90°. Thus, no work is done by the centripetal force on a body in uniform circular motion.

How much work is done by the centripetal force?

The work done by centripetal force always zero as it is perpendicular to velocity and hence instantaneous displacement.

What is the amount of work done on a body of mass 10g moving in a circular path of radius 5cm?

Answer: The work done on a body moving in a circular path is zero, because when a body moves in a circular path then thek centripetal force acts along the radius of the circle and it is at right angles to the motion of the body.

What is the work done on a body performing uniform circular motion by the centripetal force?

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules.

What is the work done on an object moving in circular motion justify?

Amount of work done is equal to zero. In the case of a body moving in a circular path, the body comes to its original place, therefore, there is no displacement, and hence work is zero.

How much is the work done by the centripetal force and why?

So, work done by a centripetal force is always zero.

What is the amount of work done to move an object in closed vertical circle on the surface of Earth?

The amount of work done to move an object in a closed vertical circle on the surface of the earth is zero because the displacement of the object is zero.

How much work is done on the ball by tension as it moves one half of the circular trajectory?

Work done by centripetal force in half revolution or quarter revolution of a particle of mass m in circular path of radius at any speed is also zero. Thus, the work done in the case of moon moving round the earth is also zero.

When a body moves in a circle the work done by the centripetal force is always zero?

Why is there no work done in circular motion?

In uniform circular motion, only the direction of the velocity is changing, because the force is at right angles to the movement. Since the speed (i.e. the magnitude of the velocity) is constant, no work is being done and the energy remains constant.

Why is the work done on an object moving with uniform circular motion zero Brainly?

Explanation: Work done is equal to Force acting in the direction of DISPLACEMENT times the displacement i.e. W=F.S where (.) is dot product. Scos(theta), since body is moving in circular track Fcos(theta)=0 , and hence whole term will be 0 i.e. Work done will be 0.

What is the work done by a body moving in circular path?

Work Done by a body moving in a circular path is Zero . ( Provided it is a uniform circular motion). This is so because, the Centripetal force on the body at any instant , is directed towards the centre of the circular path and the direction of displacement at…

How do you calculate work done on a circular path?

Work = Force × Displacement. While moving on a circular path, when we come back to the starting point, there is displacement of 0 metre. Thus, Work done = Force × 0 = 0. There is a circular path of 8 metres and we stop at halfway.

What is the amount of work done in uniform circular motion?

Physically, there is no component of force in the direction of motion. Only one component remains which does not do work at all. Hence, the work done in a uniform circular motion is always zero. Eureka! Originally Answered: what is the amount of work done, when body moves in circular path?

What is the work done by the Moon moving round the Earth?

The work done on a body moving in a circular path is also zero. This is because, when a body moves in a circular path, then the centripetal force acts along the radius of the circle, and it is at right angles to the motion of the body. Thus, the work done in the case of moon moving round the earth is also zero.
