Two objects have masses of 9 MG and 7 MG. How much does the gravitational potential energy between the objects change if the distance between them changes from 36 m to 45 m?
1 Answer
Answer:
Explanation:
A very similarly worded problem .
The formula for the gravitational potential energy between two objects is:
Note:
Let
Therefore, the change in gravitational potential energy can be written as:
We can substitute the given values into the equation:
