What is the potential energy of a 1.0 kg mass 1.0 m above the ground?

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
