Is work done in a closed path zero?

8.1—the work done in a closed path equals zero. A force that is always perpendicular to the particle displacement does zero work on the particle for any path, including a closed path. Such forces do have an effect on the particle trajectory, but not on the particle energy.

Why work done is zero when displacement is zero?

Zero work is done when the displacement of a body is zero or perpendicular (θ=900,cosθ=0) to the direction of force applied, then work done is zero. However, the displacement is in the horizontal plane. Thus, the force applied and the displacement are in perpendicular directions. So, the work done is zero.

Why work is zero when a body is moving in a closed path?

Complete step by step answer: The work done by the celestial body moon revolving around the earth in a closed circular orbit under the influence of the earth’s gravity is zero. This is because the force of gravity is a conservative and it does not depend upon the path along which work is done.

What is work done by gravitational field in closed path?

The work done in going around any path in a gravitational field is zero. This is a very remarkable result.

What force does zero work in a closed path?

conservative force
Total work done by conservative force in a closed path motion is zero.

Why work done in the motion of a body over a closed loop is zero for every force in nature?

Work done in the motion of a body over a closed loop is zero only when the body is moving under the action of conservative forces (like gravitational or electrostatic forces). It is not zero when the forces are non-conservative e.g. frictional forces etc.

When work done in moving a particle round a closed loop in a field is zero forces in field are called?

Equivalently, if a particle travels in a closed loop, the total work done (the sum of the force acting along the path multiplied by the displacement) by a conservative force is zero. A conservative force depends only on the position of the object.

What is the work done by non-conservative and conservative forces?

Work done by a non-conservative force inside an enclosed path is never zero. Work done by conservative force inside a closed loop is always nil. Non-conservative force is any force where the path taken by an object determines the work done by or against that body.

Is the state of conservative force true or false?

State true or false: A force is said to be conservative, if the work done over any closed path is zero. True. State law of conservation of energy. The law of conservation of energy states that “In a closed system, i.e., a system that is isolated from its surroundings, the total energy of the system is conserved.”

Can the work done by a gravitational force be reversed?

You can easily reverse the work completed when it comes to a force which is conservative. Therefore, work done by a gravitational force can be easily reversed. Lastly, the conservative force is only dependent on the final and initial position of the object. All other positions in between do not affect the final outcome.
