Question

If a ball is tossed straight up into the air, at what position is its potential energy the greatest?

A.when it reaches the top of its flight

   
B. when it first leaves your hand    
C. when it approaches the top of its flight    
D. when it begins to fall back to your hand.

Answer 1

A. when it reaches the top of its flight

potential energy increases as the height of the object does, and the highest point of a ball's flight is when it reaches the top.

Answer 2

A.when it reaches the top of its flight

Step-by-step explanation:

The potential energy of an object is given by:

`U=mgh`

where

m is the mass of the object

g is the acceleration of gravity

h is the heigth at which the object is located above the ground

Therefore, we see that the higher the object, the larger its potential energy: this means that the ball will have the greatest potential energy at the top of its trajectory.
