A.
It decreases because potential energy is a kind of mechanical energy.
B.
It does not change because kinetic energy and potential energy are both kinds of mechanical energy.
C.
It increases because kinetic energy is a kind of mechanical energy.
D.
It does not change because kinetic energy and potential energy are not kinds of mechanical energy.

Answer 1

a or b

Step-by-step explanation:

because those are the most likely to be true

now it gives you two options so i thinks it might be B but you could choose A you got two options choose wisely
