Best Answer

Mechanical potential energy, U, equals mgh where m is mass, g is the gravitational constant, and h is the change in height from the reference point.

Applying U=mgh this situation, you get:

U=(50 kg)(9.8 m/s2)(3 m) = 1470 Joules (J)

When a boy walks up a flight of stairs his what energy increases?

The boy's potential energy increases as he moves higher up the flight of stairs against the force of gravity.


How is potential energy delivered to you?

-- eat food -- climb a flight of stairs -- spend some time in the sunshine


When you climb up the stairs what is the energy transformation?

chemical energy (stored in the muscles of the body) turns to kinetic energy (climbing up the stairs) and then is transformed to potential energy (once you reach the top of the stairs) due to your position.


When a boy climbs steps what happened to his potential energy?

If he climbs up the stairs, his potential energy will increase.


What type of energy is used to go up stairs?

Potential energy is used when going up stairs. As you lift your body against gravity to ascend the stairs, your potential energy increases. This potential energy is then converted into kinetic energy as you move upwards.


If you were to walk down stairs would you have more potential energy at the top or at the bottom?

You would have more potential energy at the top of the stairs because your potential energy is dependent on your height relative to the ground. As you descend the stairs and move closer to the ground, your potential energy decreases.

When a person climbs stairs what form of energy is being converted into gravitational potential energy?

When a person climbs stairs, the chemical energy stored in their muscles is being converted into gravitational potential energy as they move against the force of gravity.


What is a group of stair called?

380 n girl walks down a flight of stairs so that she is 2.5 m below her starting level what is the change in the girl's gravitational potential energy?

The idea is to use the formula for gravitational potential energy, which is simply weight x height. Since the girl moves downward, the change in energy is negative in this case.
