Gravitational potential energy between 2 objects is ##-{G\times M\times m\over R}.## My question is, does the value of this equation of this equation mean...
How many joules of energy (work) are required to raise a mass of 2,500 kg by a height of 5 meters against gravity at the surface of the earth?How much potential energy does a 2.5 kg rock sitting on an 18 m high cliff have?how much potential energy does a 76 k...
Electric potential is a relative term, just like gravity, and there is no potential energy as a counterpoint it tell us it is what is the potential energy. This is the same does not pick a zero potential, it is clear that there's nothing I can do about it, how much is because, wit...
In the case of lifting a box, I know potential energy is negative because negative work is done by gravity. What does the negative part of -PE denote? Does it denote the direction of the energy or does it mean that energy is being lost? But how is energy being lost if the box gains...
Does centripetal force equal energy? Centripetal Force: Centripetal force and kinetic energy are related. Centripetal force refers to something that influences objects to move in a circular path with the center being the source of the force. A ferris wheel is an example of an object with centripe...
the human body has natural electromagnetic energy. this caninterfere with the radio signal because the body can behave as anantenna for this energy. what energy is in walking uphill? potential energy is stored in your body as you walk uphill. as you move against gravity, your body gains ...
(that EM filed attracts things gravitationally), it is true. But not because it is its mass that attracts things gravitationally but because the source of gravity is not mass alone but the energy-momentum tensor. This has 16 components of which only one is the mass. ...
Describe the methods used to examine the conservation of energy for the swinging pendulum. When is it not in equilibrium? Why is the tension force equal to mass x gravity on an inclined plane? Why does centripetal force matter? Explain why objects with different weights f...
Does inertia or friction oppose gravity? Is the relationship between the magnetic force and current linear? What is the difference between gravitational force and magnetic force? A proton moving at 4.1 x 10^6 m/s experiences a magnetic field of 3.8 T. Calculate the magnitude of the magnetic ...
ergs. An ongoing problem in cosmology concerns the fate of this energy. In one interpretation it is irretrievably lost, , where is the internal gravitational potential energy of the object. Preliminary evidence of such an energy release is presented in bodies ranging from planets, white dwarfs ...
