The diagram below shows a 4.0-kilogram object accelerating at 10. meters per second on a rough horizontal surface.
Acceleration = 10. m/s2
Frictional
force = F1
Applied
force = 50. N.
m = 4.0 kg
(Not drawn to scale)
What is the magnitude of the frictional force F, acting on the object?

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.
