At which letter does that ball have the greatest potential energy? A
B
C
D
E
F
G

A.

Step-by-step explanation:

Potential energy is energy that is collected when it has the most intention. In this case, the ball is on top of the hill, and has the potential to roll down. Ball D has the least potential because it is on the lowest part of the hill.

I'm not as sure about this one, but I THINK it's B...?

Step-by-step explanation:

You might want to double check with someone else about that one, but I think it's ball B because kinetic energy is energy in motion. If you think about it, when you roll a ball down a hill the first "dip" is where it goes fastest, thus more kinetic energy.

only 10/60 isn't equivalent

hope this : )
