A baby carriage is sitting at the top of a hill that is 36 m high. The carriage with the baby weights 15 N. What type of energy does the carriage have? Calculate the energy.

The carriage has potential energy since the carriage has the potential to fall and convert that potential energy into kinetic energy.

The potential energy in this case is 15*36 = 540 joules.

The potential energy formula is

PE = m*g*h

where mg is the weight of the object, so you can express it like this

PE = w*h

So that's why we multiply the weight with the height to get the potential energy.

prolly a beacuse the momentuem the car has increases while going down hill
