m = mass for which potential energy is to be calculated = 1.0 kg
h = height of the mass above the ground = 1.0 m
g = acceleration due to gravity acting on the mass = 9.8 m/s²
gravitational potential energy of the mass is given as \
Potential energy = mass x acceleration due to gravity x height
PE = m g h
inserting the above values in the equation
PE = (1.0) (9.8) (1.0)
PE = (9.8) (1.0)
PE = 9.8 Joules
hence the potential energy of the mass comes out to be 9.8 Joules
