How does the change in potential energy equal the work done on an object?
When the potential energy of an object changes, it is because work has been done on the object. This means that the amount of work done on the object is equal to the change in its potential energy.
What is equal to the ability to do work?
Energy is equal to the ability to do work. Energy can exist in various forms such as kinetic energy, potential energy, thermal energy, and chemical energy.
What energy of a book on a shelf is equal to the work done to lift the book to the shelf?
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
In physics is work equal to the negative of the potential energy?
Yes, work= -GmM/R This work is energy that is stored in the gravitational field of the two masses and is called the gravitational potential energy of the two masses when they are separated by a distance R: Ep= -GMm/R
The kinetic energy of a book on a shelf is equal to the work done to lift the book to the shelf?
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
How is work related to gravitational potential energy?
As we lift a body of mass m from ground level to a height h, then work performed will be mgh which is equal to the difference in gravitational potential energy at the ground level and at that height.
Function of an engine?
Converts chemical potential energy in the fuel to mechanical work at the shaft.
How much work is done in rotating a dipole from stable to unstable equillibrium?
In rotating a dipole from stable to unstable equilibrium, the work done is equal to the change in potential energy. As the dipole is moved, the electrostatic potential energy of the system changes, resulting in work being performed on the dipole. The amount of work done is equal to the difference in potential energy between the two equilibrium positions.
Light with an energy equal to three times the work function of a given metal causes the metal to eject photoelectrons. What is the ratio of the maximum photoelectron kinetic energy to the work functio?
The maximum photoelectron kinetic energy is given by the equation: Energy of incident light - Work function. If the energy of the incident light is three times the work function, then the maximum kinetic energy of the photoelectrons will be three times the work function. Therefore, the ratio of the maximum photoelectron kinetic energy to the work function is 3:1.
When two children of equal weight sit at opposite ends at a seesaw do they create work and energy?
No, when two children of equal weight sit at opposite ends of a seesaw, they do not create any work or energy. Since they balance each other out, there is no net force acting on the system and therefore no work is done. Energy is also conserved as the potential energy one child gains is equal to the potential energy the other child loses.
How does kinetic energy and potential energy switch?
work=change in kinetic energy, doing work on an object by moving it up increases that object's potential energy because it has the POTENTIAL to fall due to gravity. kinetic energy is lost in the movement of the object. However, throughout an entire closed system, the total energy in joules (or kinetic enery plus potential energy) does remain constant. this is useful because the initial energy and the final energy most be equal, and if thats true, then initial kinetic energy plus initial potential energy must equal final kinetic energy plus final potential energy. does that help?
What is energy that has the potential to do work?
Potential energy
