Mary weighs 533 Nand she walks down a flight of stairs 4m below her starting point what is the change in marys potential energy?
That's a mighty heavy woman! Anyway, potential energy is calculated as mgh, that is, mass x gravity x height. To calculate in SI units, mass should be in kilograms, gravity is about 9.8 meters per second square, and height in meters. Since she goes down, the change in potential energy is negative - her negative energy decreases.

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.
What physical quantity remains unchanged during the flight of an oblique projectile?
The total mechanical energy of the projectile remains unchanged during its flight. This includes both kinetic energy and potential energy.
Is a bird in a flight potential or kinetic energy?
When a bird is in flight, it is primarily exhibiting kinetic energy, which is the energy of motion. As the bird moves through the air, it has both forward velocity and lift, both of which contribute to its kinetic energy.
A girl weighs 380-n and walks down a flight of stairs she is 2.5 m below her starting level.what is the change in th egirls gravitional potentional energy?
The change in the girl's gravitational potential energy is given by the formula ΔPE = m * g * Δh, where m is the mass, g is the acceleration due to gravity and Δh is the change in height. From the given information, the girl's weight (mg) is 380 N, the change in height (Δh) is 2.5 m, and the acceleration due to gravity (g) is 9.81 m/s^2. Plug these values into the formula to calculate the change in the girl's gravitational potential energy.
What is a riddle for potential energy?
I am lifted high, but not in flight, Awaiting release with all my might. Stored as potential in a state so tight, What am I, waiting to take my height?
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.

How is potential energy delivered to you?
-- eat food -- climb a flight of stairs -- spend some time in the sunshine
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)

Can an airline change your flight time without notice?
Yes, an airline can change your flight time without notice due to various reasons such as schedule adjustments, operational issues, or weather conditions. It is important to check your flight status regularly and be prepared for potential changes.
Energy changes in a moving airplane?
In a moving airplane, energy changes primarily occur between kinetic energy and potential energy. As the aircraft ascends, kinetic energy is converted into potential energy, allowing it to gain altitude. Conversely, during descent, potential energy is converted back into kinetic energy, increasing speed. Additionally, engines convert fuel's chemical energy into kinetic energy for propulsion, while aerodynamic forces manage energy efficiency during flight.
Why do rockets have potential energy?
Rockets have potential energy because they store chemical energy in their fuel, which is converted into kinetic energy as the rocket propels forward. As the fuel is burned and expelled out of the rocket, it pushes against the ground or atmosphere, causing the rocket to move and lift off the ground.
How can I change my flight without paying a fee?
To change your flight without paying a fee, you can try to make the change within 24 hours of booking, look for flexible fare options, or consider joining the airline's loyalty program for potential waiver of fees. Additionally, some credit cards offer benefits that may help you change your flight without incurring extra charges.
