energy is the ability to do work while work is the dot product of force and displacement
Explanation:
In order to calculate the work from r = a to r = b we only need to convert 1000 km into 1,000,000 m.
Since, the given data is as follows.
G =
= 1000 kg
a =
b =
=
Now, we will calculate the work as follows.
W =
=
=
thus, we can conclude that work required to launch the satellite is .
Energy can be released and absorbed during the formation of a solution, not one or the other. When a solute interacts with the solvent, energy is absorbed so the solvent can overcome the intermolecular bonds of the solute and energy is released, most commonly, in the form of heat, light, or a gaseous byproduct.
Gravity. All objects have a force that attracts them towards each other. This is called gravity
