Lucas plugs a lamp into the wall. the light bulb in the lamp turns on. what kind of energy transformation is this? a.)light energy is transformed into electrical and mechanical energy. b.) light energy is transformed into mechanical and heat energy. c.) electrical energy is transformed into light and heat energy. d.) electrical energy is transformed into mechanical and heat energy.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
