A pendulum has 501 J of potential energy at the highest point of its swing. How much kinetic energy will it have at the bottom of its swing? joules

501J at the bottom

To find the kinetic energy of the pendulum at the bottom of its swing, we can start by knowing that the total mechanical energy of the pendulum is conserved throughout its motion. Mechanical energy is the sum of potential energy and kinetic energy.

At the highest point of the pendulum's swing, all of its potential energy is stored and there is no kinetic energy. Therefore, the potential energy at the highest point is equal to the total mechanical energy:

Potential energy at highest point = Total mechanical energy

Given that the potential energy at the highest point is 501 J, we can write this equation as:

501 J = Total mechanical energy

Now, at the bottom of the swing, all of the potential energy will be converted into kinetic energy. Therefore, the kinetic energy at the bottom of the swing will be equal to the total mechanical energy.

Hence, the kinetic energy at the bottom of the swing will also be 501 J.
