Answer from: Quest
You get 6 for mechanical
Answer from: Quest
an energy transformation flow diagram is shown
where is it ?
Answer from: Quest
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.
mass:
