Answer:
The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Explanation:
Answer:
Explanation:
KE = mv²/2 or (1/2)mv²
so assume v = 2 and m = 3 then the KE would be 6. Now assume v = 2 and m = 2 then KE would be 4, so the KE increases if the mass increases and velocity is constant.
PE = mgh
g = 10 assume h = 10 and m = 10
then PE = 1000
now g = 10 h = 10 but m = 5
then PE = 500 so, if m decreases, pe also decreases
