If a boy of a mass 50 kg runs up a flight of stairs in 3s If the flight is 3m high calculate his gain in potential energy?

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)

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.
Is a fleet of stairs correct?
NO. Use "flight of stairs"
How many steps make a flight of stairs?
A flight of stairs is an uninterrupted set of steps. The answer could be the same or different for any given flight of stairs! A flight of stairs is an uninterrupted set of steps. The answer could be the same or different for any given flight of stairs!
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.
A group of stairs?
A group of stairs is referred to as a flight. Example in a sentence- I followed him up a flight of stairs.
What is a group of stair called?
Flight of stairs and Fleet of ships.
Can you fall up?
No, falling up the stairs is a common grammatical error. The proper expression is tripping up the stairs. You cannon fall up because according to physics: 1. Energy = potential energy + kinetic energy but energy is always the same and constant 2. When you fall kinetic energy increases and so in order for energy to remain the same potential energy must decrese. 3. Potential energy is equal to the mass, gravity, and height. Since mass and gravity are not changing but potential energy is the height then MUST decrease.
Which action uses more energy walking up a flight of stairs or watching tv?
watching tv
What is a pair of stairs?
A pair of stairs is another term for a flight of stairs.
If you exert a force of 700 N to walk 6 m up a flight of stairs in 6 s how much power do you use?
Calculate the energy required to raise the person (weight x height). Then divide that energy by the time, to get power.
