QUESTION:
Figure 7.22b shows the potential-energy function associated with the gravitational force between an object and the earth. Use this graph to explain why objects always fall toward the earth when they are released.
ANSWER:Solution 19DQ
Step 1:
From the graph, we can see that, if a body is projected upward for a height “y”, the body will acquire a potential energy at that height and it will be,
U = mgy
Where, m - mass of the body
g - acceleration due to gravity
