You wanted to design a doorbell system that was able to differentiate between the front door and the back door with a different sound, but the entire system was housed in the same unit. How would your design have to change in order to make that possible? Describe your new unit OR draw a detailed picture including labels for your new doorbell.

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.
