Absolute Potential Energy: Absolute potential energy is the potential energy needed to be applied on an object to displace it to such a distance where gravitational force doesn't work on it.
Mathematically
U=(-GMm)/r
Here
U is absolute potential energy
G is Gravitational constant whose value is 6.673 x 10-11
M is mass of earth whose value is 5.9736 x 1024
m is mass of the mobile object.
r is distance between center of earth and object.

Gravitational Potential Energy PE = mgh
We can calculate gravitational force in small parts. F=GMm/r2
If we move one object from 0 point to 1 as shown in figure
then r1 is the distance from 0 to 1 and r2 is is the distance from point 0 to 2.
r = r1 + r2 / 2
∆r=r2-r1, r2 = ∆r + r1
r = r1 + ∆r + r1/2 =2r1 + ∆r /2 = r1 + ∆r /2 …show more content…

What is her average power cut put, in watts? In kilowatts?
A. mass = 50kg
time = 15 minuts or 900 sec
g = 9.8 m/s2
Sears tower height = 442 m
P = ?
p = f x d/t
f =mg2
f =50 x 9.8
f = 490
