Question

As a pendulum swings from the bottom position to the top position

kinetic energy is changed into potential energy

mechanical energy is changed into radiation

radiation is changed into friction

potential energy is changed into kinetic energy

Answer 1

I think it's A)

Step-by-step explanation:

it could be wrong i don't know hope it's not good luck!

Answer 2

Actually Welcome to the Concept of the Power and Energy.

As a pendulum swings from the bottom position to the top position, it gains a height which means it gains the Potential energy.

hence we can say that, kinetic energy is changed into potential energy.

So, the Option A.) is correct.
