A pendulum is oscillating on either side of its rest position. Explain the energy changes that take place in the Oscillating pendulum. How does mechanical energy remain constant in it ? Draw the necessary diagram.

A pendulum is oscillaring on either side its rest position.The correct statement is:

How does energy change take place in a physical change? Explain.

Draw a diagram to show the energy changes in an oscillating simple pendulum. Indicate in your diagram how the total mechanical energy in it remains constant during the oscillation.

A pendulum with bob of mass is scillating on either side from its resting position A between the extremes B and Cala vertical height above A. What is the kinetic energy K and potential energy U when the pendulum is al positions (i) A. (ii) B. and (in C?

(a) What is mechanical energy ? (b) What kind of energy changes take place in the bodies of living beings, so as to produce mechanical energy.

If the speed of a car is halved, how does its kinetic energy change?

Explain the energy changes taking place in the following situations: (a) Switching on a flash light. (b) Using coal to generate electricity.

A pendulum has a period T for small oscillations. An obstacle is placed directly beneath the pivot, so that only the lowest one - quarter of the string can follow the pendulum bob when it swings to the left of its resting position. The pendulum is released from rest at a certain point. How long will it take to return to that point again ? In answering this question, you may assume that the angle between the moving string and the vertical stays small throughout the motion.
