What is the gravitational potential energy of a # 1 kg# object on a shelf # 1/8 m # high? Physics Work and Energy Energy 1 Answer Shwetank Mauria Feb 20, 2016 #1.225# Joules Explanation: Potential energy #PE# is given by #m*g*h# where #m# is mass in kg, #g# is acceleration due to gravity #9.8m/s^2# and #h# is height in meters. Hence #PE# is #1*1/8*9.8# or #1.225# Joules. Answer link Related questions How do matter and energy interact? Question #50ca2 Question #242cf Question #5038d Question #50391 What is potential energy?
