Answer:
The same book on a table has more potential energy.
Explanation:
The potential energy of a body on Earth is defined as the energy possessed by the virtue of its heights.
The equation for gravitation potential energy is given by
P.E = mgh joules
From the above equation it is evident that when there is a change in the value of 'h', there is a change in the value of P.E
So, as per the above equation, the potential energy of book on floor
P.E = m x g x 0 ∵ h = 0 at floor
P.E = 0
The same book on the table has some magnitude in 'h' greater than zero
So, the same book on a table has more potential energy.
