The work done by restoring force during one complete oscillation is equal to?
ایک مکمل ارتعاش کے دوران بحال کرنے والی قوت کا کیا گیا کام کتنا ہوتا ہے؟
- K.E of pendulum
- Zero
- P.E of pendulum
- None of these
Explanation
- During one complete oscillation, the pendulum returns to its initial position, so its net change in potential energy is zero.
- The work done by the restoring force over a complete cycle is zero.
- Because the energy gained during one part of the motion is balanced by the energy lost during the other part.
- At the extreme positions, the pendulum has maximum potential energy and zero kinetic energy.
- At the mean position, its kinetic energy is maximum and potential energy is minimum.
