Aforce vec f =f x hat i +f y hat j acts on a particle that undergoes a displacement of vec s =s x hat i +s y hat j where f x =7 n , f y =-3 n , s x =4 m , and s y =1 m . find the work done by the force on the particle . answer in units of j.

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.
