0.5 kg mass on a 1 m long string swings in a circle on a horizontal, frictionless table at a steady speed of 2 m/s. how much work does the tension in the string do on the mass during one revolution?

0 joule work done does the tension in the string do on the mass during one revolution

Mass =0.5 kg.

Displacement = 1 m.

T=tension

[tex]\theta=90[/tex]

work done= Tcos90

cos90=0

work done=T×0

work done=0 joule

When an item is moved across a distance by an external force, at least a portion of that force must be applied in the direction of the displacement. This is known as work done in physics. By multiplying the length of the path by the component of the force operating along the path, work may be calculated if the force is constant. The work W is equal to the force f times the distance h, or W = mgh, to mathematically describe this idea. The work is W = mgcos if the force is applied at an angle of to the displacement.
