The total energy in a system is 675 J. The kinetic 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.


It changes from 432 J to 296 J.


It changes from 243 J to 379 J.

Verified Answer :

By definition, the Total energy is given by:


\(E = U + K
\)

Where,

U: potential energy

K: kinetic energy

We look for the value of the potential energy for the different values of the kinetic energy.

We have then:

For K = 296:

\(U = E - K

U = 675 - 296

U = 379
\)

For K = 432:

\(U = E - K

U = 675 - 432

U = 243
\)

Therefore, the change in power power is from 379 J to 243 J

Answer:

It changes from 379 J to 243 J.
