The total energy in a system is 675 J. The kinethe energy changes from 296 J to 432 J. Which statement best describes the

potential energy of this system?

It changes from 296 J to 432 J.

It changes from 379 J to 243 J.

O It changes from 432 J to 296 J.

O It changes from 243 J to 379 J.

The potential energy changes from 379 J to 243 J

Explanation:

We have,

Total energy in a system is 675 J.

The kinetic energy changes from 296 J to 432 J.

Total energy is the sum of kinetic energy and the potential energy.

If kinetic energy is 296 J then,

P = 675 - 296 = 379 J

If kinetic energy is 432 J then,

P = 675 - 432 = 243 J

So, the potential energy changes from 379 J to 243 J. Correct option is (b).
