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

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
