which bet explains why the shape of a liquid can change? 1. the particles have just enough energy to move past each other. 2. the particles are charged. 3. the particles move at very high speeds at all times. 4. the particles are highly compressable

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.
