How to Calculate the potential energy of a falling object?
Gravitational potential energy (GPE) is essentially a measure of stored energy. It is defined as being a function of gravity (9.8m/s2 on Earth), mass and perpedicular distance above the ground.Since work is a measure of energy the GPE is a measure of potential work. Work is defined as:Work = Force * Distance = FdNewton's laws of motion are then used to replace force with some function of mass and acceleration due to gravity:Force = Mass * Acceleration = maor, in this case,Force = Mass * Gravity = mgTherefore:GPE = Mass * Gravity * Distance = mgdFor a falling object it is losing potential energy as it moves closer to the ground (because the distance value in the equation above is reducing) so the distance between the object and the ground defines the remaining GPE of the falling object for the remainder of the fall after this point. This equation will only tell you the GPE relative to distance from the ground, as mass and gravity are constants.If you wanted to take that a bit further you can factor in the speed of falling and derive equations to calculate the GPE at a specific time interval relative to when the object is released. To do this we need Newton's equations of motion (I've cancelled out and modified the below equation for simplicity):Distance = ( Gravity * Time * Time ) / 2 = 0.5gt2Plugging this into the GPE equation we get,Remaining GPE = mg(d-0.5gt2)Examples:So if an object with a mass of 100kg is held at 50m above the ground on Earth it will have a GPE of:GPE = mgd = 100 * 9.8 * 50 = 49.00kJIf the object is released and we want to know the remaining GPE after 1 second:Remaining GPE = mg(d-0.5gt2) = 100 * 9.8 * ( 50 - ( 0.5 * 9.8 * 12 ) ) = 44.20kJRemaining GPE after 2 seconds:Remaining GPE = mg(d-0.5gt2) = 100 * 9.8 * ( 50 - ( 0.5 * 9.8 * 22 ) ) = 29.79kJ
How does gravitational potential energy of an object increase?
On Earth, Gravitational Potential Energy (GPE) would increase with an increasing altitude.
What is gravitatinal potetial energy?
That refers to potential energy related to a gravitational field. In simple terms, an object that is higher up has more energy than one that is lower. This energy can be converted into other energy types; for example, when an object falls down, its potential energy is converted to kinetic energy (i.e., movement). The formula for gravitational potential energy is: GPE = wh (weight x height) or equivalently: GPE = mgh (mass x gravity x height)
When a lump of clay is dropped what energy transformations occur?
potential to kinetic to mechanical When clay lands, kinetic (because object is in motion [newton's first law]) to potential
What is GPE in physics?
Gravitational Potential Energy
Can the gravitational potential energy of an object ever have a negative value?
it is conventional to define gravitational potential energy (GPE) of object A to be 0 when the object is free from the gravitational field of object B (i.e. at a infinite distance away) As the objects get closer together, the GPE decreases, thus is less than 0. Therefore the GPE of any object normally has a negative value (however it all just depends on where you define to be the point at which the object has 0 GPE)
How do you find the mass of an object if you have its height and gravitational potential energy?
GPE = Mass * Height so Mass = GPE/Height
If you have lost sound energy how does that affect the total gravitational potential energy?
It does not. GPE depends only on the height of the object over some reference level, and the gravitational attraction.It does not.

What is the formula of calculating GPE?
The correct formula for solving GPE (Gravitational Potential Energy) is as follows: ~GPE = wh ~Gravitational Potential Energy = weight of an object multiplied by height of an object ~The SI unit for this formula is *J* (Joules)
What gives something potintial energy?
Potential energy is the theory that an object has energy that can be released. Gravitational Potential Energy is an example of this. GPE is obtained as you gain height, the more height, the more GPE.
The stored energy an object has a result of its height above the ground is?
Gravitational potential energy or GPE.
What is the gravitational potential energy of an object is equal to its weight multiplied by its?
The gravitational potential energy is equal to: GPE = mass x gravity x height Or equivalently: GPE = weight x height

How does the position of an object affect potential energy?
The position of an object affects its gravitational potential energy (or GPE) because GPE is calculated by multiplying mass by the value for gravity (on Earth it's 9.81) and the objects height. The higher up an object is the more potential energy it will have because it has farther to fall.
What is formula for GPE?
GPE=weight x height
How does gravitational potential energy of an object increase?
On Earth, Gravitational Potential Energy (GPE) would increase with an increasing altitude.
Is the gravitational potential energy of the object dependent to the mass?
Yes. GPE = mgh (mass x gravity x height).
