Question

Write down your design of a simple experiment to test the law of conservation of energy. Your design should include a list of necessary equipment and a brief description of a procedure.

List of equipment:

Description of Procedure:

Answer 1

List of equipment:

1.measuring tape

2 inclined surface

3. A spherical ball

4. Velocity measuring device

Description of procedure:

Put the spherical ball on the top of the inclined surface and measure the vertical distance of the spherical ball from the ground

Release the ball from the inclined surface and measure the velocity of the ball at the bottom with the velocity measuring device

Now when the ball is at the top it will ha e the potential energy and it can be calculated by

P.E=mgh

At the end of the inclined end plane it will have kinetic energy given by

K.E=½mv²

Both PE at the top and the KE at the bottom will be same

Proving the law of conservation of energy
