Listenan object gains 10. joules of potential energy as it is lifted vertically 2.0 meters. if a second object with one-half the mass is lifted vertically 2.0 meters, the potential energy gained by the second object will be10. j20. j5.0 j2.5 j

5. J

Explanation:

Given:

As we know that potential energy is given as:

So proportionally the the potential energy gain by the second mass:

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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.
