If a pendulum has 45 Joules of total energy, how many joules of kinetic energy would it have at the bottom of its swing?
Group of answer choices

25 Joules

45 Joules

0 Joules

15 Joules

The law of conservation of energy says that energy is not created or destroyed, but transformed. This means that if I have a certain amount of energy and it becomes another, then it is exactly the same in quantity.

In this case as we have 45J of energy that is transformed into kinetic energy, then the answer is 45J

We conclude that the correct answer is option b: 45J
