Why is the work done on an object moving with uniform circular motion zero meaning in Marathi?

Work done on an object is the product of force applied and the displacement covered in the direction of force applied. Hence, the work done in a uniform circular motion is always zero.

Why is the work done by a centripetal force always equal to zero?

The centripetal force is always towards the center of the circular path and is responsible to restrict the particle to move in a circle and not responsible for the displacement of the particle. No displacement takes place in this case. So, work done by a centripetal force is always zero.

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

The work done by a object in the circular path is zero, because, in case of circle, the net displacement is always zero. Another reason being it zero, is in circular path, CENTRIPETAL FORCE ACTS on the along the radius of the circle, which is right angle to the motion of body.

Why is no work done in uniform 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?

Work is done when a force is applied to an object through a distance. This means that when a force is applied to an object through a distance, the object’s total energy will be affected.

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

zero
A : When a body moves in a circle the work done by the centripetal force is always zero.

When a body moves in a circle the work done by the centripetal force is always zero R centripetal force is perpendicular to displacement at every instant?

Assertion : Work done by the centripetal force in moving a body along a circle is always zero. Reason : Because displacement of the body is along the force. A body is kept moving with uniform speed in a circle by a centripetal force acting on it. However the work done by this force is zero.

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.

Is work done in uniform circular motion?

Why is displacement zero in a circular motion?

From the definition, it is clear that displacement to be considered is in between only one point, which turns out to be zero. Therefore, we can come to the conclusion that the displacement in one cycle of a circular motion is zero.

Why is the work done on an object moving uniformly zero?

Why is the work done on an object moving with uniform circular motion zero? In circular motion, the direction of force acting on the object is radially inward and the direction of motion of the object is tangential to the circular path at every instant of time.

Why work done by centripetal force is zero in uniform circular motion?

For an object moving in uniform circular motion, the only force is the centripetal force, which points in a direction along the radius of the circle, and since the radius of the circle never changes, there is no displacement along this direction, and the work done by this force is zero.

How is work done on an object given in circular motion?

Work done on an object is given as `W = F xx S costheta` In circular motion, the direction of force acting on the object is radially inward and the direction of motion of the object is tangential to the circular path at every instant of time.

What is the component of force along the direction of displacement?

 For the work done we need component of force along the direction of displacement but displacement and force are 90°, at each and every point on the circular track and therefore the component of force along the direction of displacement will always be zero in case of a body moving in a circular track or a body performing circular motion.
