Gravitational Potential Energy (GPE) = Mass (m) x Gravity (g) x Height (h) Now assuming g = 9.8ms-2 we can rearrange the formula to give us our answer, so the formula becomes: h = GPE/m x g h = 40/2 x 9.8 h = 2.04 metres

How is gravitational potential energy related to height?
Approximately, but not quite precisely, linearly.
A 20 kg mass is held above the ground What is the approximate potential energy of the mass with respect to the ground?
The potential energy, expressed in joules, is 196 times its height above ground, expressed in meters.
How many joules of potential energy does a 1-N book gain when it is elevated 4 m?
A 1-newton book at 4 meters gains approximately 4 joules of potential energy.
What is potential and potential difference?
You can compare 'potential' with the height of an object, and 'potential difference' with the difference in height between two objects.Height is not absolute, we always specify height with respect to some point of reference, such as 'sea level'. Objects above sea level we can designate as, for example, plus 1000 metres; objects below sea level we can designate as, for example, minus 500 metres.The difference in height between these to objects will be +1000 - (-500) = 1500 metres.In much the same way, potential depends upon from where it is measured. In many cases, we measure potential with respect to earth, although we could use any other reference point, in which case its potential would be different. For example one object may have a potential of +1000 V with respect to earth, while another has a potential of -500 V with respect to earth.The potential difference between these two objects will be +1000 - (-500) = 1500 V.To summarise, potential exists at a single point, and is always measured with respect to another point, such as earth. Potential is always assigned a polarity with respect to its point of reference. Potential difference is the difference in the potentials at two different points, and does not have polarity assigned to it (do not confuse 'sense' -the direction in which it acts- with 'polarity').Finally, 'voltage' is another name for potential difference, not potential. It would be incorrect to ask "What is the voltage at this point with respect to earth".
What is the potential energy of a 50kg object that is hanging 10 meters off the ground?
Use the formula: PE = mgh (potential energy = mass x gravity x height). Gravity is approximately 9.8.
What is the gravitational potential energy with respect to the surface of the water of a 75.0 kilogram diver located 3.00 meters above the water?
Gravitational potential energy = m*g*h = 75*9.8*3 = 2205 Newtons.
What is potentian energy?
Potential energy is the energy of a system or of a body with respect to the arrangement of the particles of the system or position of the body.
What height would a car have the most potential energy?
The higher it is located, the more potential energy it has.
Why potential energy varies with respect to height?
That's how potential energy is defined in the first place. Also, an object at a greater height does indeed have energy, that can be converted into other types of energy, e.g. movement.
What type of energy is located a the top of an waterfall?
Gravitational potential energy.
Can objects have potential and kinetic energy at the same time?
a body cannot have both kinetic and potential energy at the same time because, a moving body can only possess kinetic energy at a time, but potential energy is one possessed by a body with respect to its possition.
How do the different forms of potential energy depend on an objects position?
Potential energy of a body with certain mass is proportional to the vertical position of the body with respect to the ground. Potential energy of the string is proportional to second degree of displacement from the point of equilibrium.
How is gravitational potential energy related to height?
Approximately, but not quite precisely, linearly.
The deferent between potentel enery and kinetic energy?
Potential energy is defined as the energy of a system or body with respect to the position of the particles of the system or the body. Kinetic energy is defined as the energy of a system or body with respect to the motion of the particles of the system or body.
When did the potential energy of the ball begin to change to kinetic energy?
when the position of the BALL is changed WITH RESPECT TO HEIGHT then P.E change in to K.E
A 20 kg mass is held above the ground What is the approximate potential energy of the mass with respect to the ground?
The potential energy, expressed in joules, is 196 times its height above ground, expressed in meters.
Where would the most potential energy be located on a roller coaster?
At the peak.
