As a substance freezes, its temperature does not change. how does the potential energy of the molecules of the
substance change as a result of the heat released? what type of energy must decrease in order for the temperature to
decrease? (4 points)

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:

formula.

example:

given values:

mass = 0.3 kg.

dang that balls went far

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
