When an object is lifted where does the potential energy come from?
Elastic potential energy can be found when you are stretching a spring. Any kind of elastic energy can be found when you are stretching or compressing an object.
What is gravataional energy?
Answer: it is the force that pulls you down when you jump Answer: When you push an object up, you are doing work (transferring energy) against the gravitational pull. This energy is stored in the object (or, more precisely, in the system Earth-object), as potential energy - more precisely, as gravitational potential energy. Do some reading on "potential energy" for more details.
Why can work be thought of as a transfer of energy?
motion
If a proton moved from 0 V potential to 5 V potential would its potential energy increase or decrease?
Electric field points from high potential to low potential. Positive particles had tendency to follow electric field. If you are moving the particle against this tendency you are doing work, and this work give more potential energy to the particle.
How does doing work on an object change its energy?
doing work changes the energy because energy is begining transferred to the object and the power will be equal to the amount of energy transferred.
What cause an object to have potential energy?
Potential energy is stored energy capable of doing work. Since energy is general comes from the food we eat, so does potential energy.

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 about?
Energy is often defined as the potential for doing work

How might the potential energy of water in a dam be increased?
By filling the dam with more water, because by doing that it gains more gravitational potential energy which is the same as potential energy.
How is potential energy similar to kinetic energy?
Mass Kinetic energy = 1/2 · mass ∙velocity2 Potential energy = mass ∙ (acceleration due to gravity) ∙ height Mass is common to both Kinetic energy is the energy due to motion. The faster an object (mass) is moving; the more Kinetic energy is has. Potential energy is the energy due to position. The higher an object (mass) is off the earth's surface, the more Potential energy it has.fcfytrdddrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrdrtdjgrfxnzsdfcxzdfgv dorkk
Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.
Can you change potential energy of a body without doing any work on it?
No, the energy has to come from somewhere. In a mechanical case, like lifting a weight or compressing a spring, the work done is Force x Distance, and this goes to increasing the object's potential energy. In an electrical case, such as charging a capacitor, the energy put in is the watts of the supply times the time it applies.
