When the bell begins to move in the opposite direction, the compressions and rarefactions will be reversed.
A sound wave will be created, as shown below. This type of wave is called a compressional
wave, which is also known as a longitudinal wave.

Pick out all of the numbers that are compressions in the sound wave above, moving from left
to right on the wave. Pick out of all of the numbers that are rarefactions in the sound wave
above, moving from right to left on the wave. This 9-digit number is the combination for the
lock to the next page of this escape activity.

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.
