Students are lifting a 120 N block up using a lever. The distance from the block to the fulcrum is 2 meters and the distance from the fulcrum to the end that needs to be pushed down by the student is 10 meters. What is the mechanical advantage of the lever based on the location of the fulcrum.
A. 5
B. 10
C. 12
D. 60

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.
