Why is putting a book bag on a desk a form of energy?
A book bag on a desk has potential energy. That potential energy is due to its height above the ground. That potential energy is given by the formula Ep = mgh, where m is the object's mass, g is the acceleration due to gravity, and h is the height.
The energy that is given to an object that is lifted?
Potential energy is the energy of location. Gravitational potential energy is given by lifting an object, and is defined by the equation Ep = mgh, or mass * acceleration due to gravity * height.
What are some factors that affect potential energy?
(Gravitational) potential energy = mgh (mass x gravity x height). Those are the three factors. In standard units (SI), mass is given in kg., gravity is around 9.8 meter / second square, and the height should be given in meters.
What is the formula of gravitational force?
Gravitational Potential Energy has the formula Es = - GmM/r.Change in Potential Energy by HeightThe energy of gravitational potential (in joules) is given by mass (in kilograms) multiplied by height (in meters) multiplied by the strength of the gravitational field (in newtons per kilogram).On earth, gravitational field strength (g) equals about 9.81Nkg-1. This estimate should be used because g depends in complex ways upon your latitude, altitude and local topography.So use GPE = mgh = 9.81(m)(h)Gravitational Potential Energy= Gravity(9.81) x Mass(kg) x Height (m)**Strictly speaking this is the change in energy as dependent on a change in height. it also can be GPE=mgh.The formula for gravitational potential energy is - GPE (J) = mass (kg) x gravitational field strength (or 'g') (N/kg) x height (m).
What is a type of energy stored in a object because of its position?
That would be 'potential energy'. For example a mass at some hight has potential energy from gravity, which would be converted to other forms if it fell. Other examples would be a charge in an electric field, or a quark very close to another (anti)quark or two.

What would be the skaters speed if all the potential energy could be converted into kinetic energy?
Clearly, that depends on the amount of potential energy. If given the height, calculate the potential energy with the formula for gravitational potential energy (PE = mgh). If mass is not given, you can assume any mass (it doesn't affect the result), or use a variable "m". Then, assuming it gets converted to kinetic energy, use the formula for kinetic energy (KE = (1/2)mv2), replace the KE with the energy you calculated before, and solve for v (the speed).

What is your weight in newtons and what is the height of the hill when the given potential energy and mass?
One's weight in newtons is the size of the force of gravity acting upon one's centre of mass. That is your weight in kg times the gravitational constant (10 or 9.81 based on which course you take). To get your weight in kg, you have to multipy your weight in lbs by .4536 The formula of getting potential energy is m*g*h, where m is the object's weight in kg, g is the gravitational constant (9.81 m/s2), and h is the height of the hill, if the potential energy is given in Joules (kg*m2/s2). To get the height of the hill, you have to divide potential energy by mass times gravitational constant, so the formula is Epot/(m*g) = h, where Epot is the potential energy.

How do you calculate for the height of a body above the ground given the body of mass and the potential energy?
If this body is on earth, than the potential energy is the gravitational potential energy, U which equals mgy. M is the mass of the body, g is the acceleration of gravity, 9.8 ((m/s)/s), and y is the height. Thus, U = mgy. To solve for height, divide both sides by mg. y=U/mg

What is the potential energy of a 20-kg rock?
Potential energy is defined as the energy possessed by a body due to its position in the gravitational field. Approximately it will be got by using the expression mgh. m - the mass in kg g-acceleration due to gravity and h - the height above the surface of the earth The other to find the potential energy so precisely is using the expression G Mm/(R+h)2 or replacing GM by gR2 we get mg(R/R+h)2 Any way the details about h is not given. So finding the potential energy will be in complete.
What the amount of energy it takes to lift a box might be a function of?
The amount of energy is given by the formula for gravitational potential energy:GPE = mgh That is, it depends on mass, gravity, and height.
What happens to potential energy when rock falls?
When the rock is high up but has not been dropped yet, it has a lot of gravitational potential energy because of its position. PE = (mass) x (G) x (height) After it is dropped, the lower it goes, the less potential energy it has. That bit of missing potential energy has become the kinetic energy that it now has on account of its speed of descent. KE = 1/2 (mass) x (speed)2
How do you calculate energy input for lifting objects by weight and height lifted?
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
