How do solids, liquids, and gases change from one state to another? What makes water (H2O) a simple type of matter to work with here on Earth?

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.

example:

given values:

mass = 0.3 kg.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
