Question

In which of the following situations is his kinetic energy being transformed into potential energy?
A.
when his height and speed are both equal to zero
B.
when his height is increasing and his speed is decreasing
C.
when his height is not changing and his speed is zero
D.
when his speed is increasing and his height is decreasing

Answer 1

so, as you should know, kinetic energy is when something is in motion.
if we want the kinetic to transform into potential, we are going to be looking for an option where speed/motion is decreasing. this eliminates "D".
so when i think of potential energy, i think of a ball being held up in the air, and there is potential energy before it is released. In this case, we will look for an option where the height increases.
looking at the options, the best one is "b"

Answer 2

Nice but let the person figure it out next time. I mean like don't give direct answers

Answer 3

ok
