Question

consider a ball thrown straight up in the air. at what position is its kinetic energy a maximum? as soon as it leaves the hand halfway up and rising at the zenith halfway up and falling where is its gravitational potential energy a maximum? as soon as it leaves the hand halfway up and rising at the zenith halfway up and falling

Answer 1

Kinetic Energy + Potential Energy = Constant

When the ball is released, the potential energy is zero and the kinetic energy is a maximum.

M g H is a measure of potential energy - the smaller height, the greater the kinetic energy.
