What three things does gravitational kineicenergy depend on?
The concept of Gravitational Kinetic Energy is has three components that it is dependent upon. The volume, the mass and the heat of the elements that are part of the reference frame when looking the inner workings of this energy.
What would the kinetic energy of a rock sitting on the ground be?
Zero. You need to think in terms of "frame of reference" as in what are you comparing the rock to. If you are an observer sitting next to the rock then the kinetic energy of the rock RELATIVE TO YOU is zero - I.E. the rock isn't moving relative to you and thus has no kinetic energy - energy of motion - relative to you. If you are an observer sitting a million miles from earth watching the rock then it is zipping around at 1000 miles per hour as the earth spins on its axis and it has significant kinetic energy RELATIVE TO YOU.

Does a person standing motionless in the aisle of a moving bus have kinetic energy?
Velocity depends on the point of view, or as they say in physics, on the "frame of reference". The amount of kinetic energy depends on velocity, and therefore, it also depends on the frame of reference.From the point of view of someone else who is also standing in the bus, such as person would have zero velocity and zero kinetic energy. From the point of view of one who watches the bus from the outside (standing still, near the road for example), the velocity, and therefore also the kinetic energy, of the person being considered will be non-zero.
What happens to speed if kinetic energy halved?
Kinetic energy is determined by mass and velocity. The velocity is halved if you double the original mass, so the kinetic energy stays the same (unless the mass added has the same kinetic energy in the observer's reference frame as the original mass).
Can electric flux be negative?
Potential energy has to be defined within a frame of reference (much like motion is relative). So if you define "the ground" as 0 gravitational potential energy, then anything sitting on the ground will have 0 potential energy. There is really no such thing as an "absolute potential energy" anymore than there is a body that is absolutely stationary (at rest, 0 kinetic energy, without regard to frame of reference). All motion is relative, as is potential energy.
Is standing kinetic or potential energy?
It is not kinetic energy. Whether or not it is potential energy depends on the frame of reference.
Does the Kinetic Energy of an object depends on the frame of reference in which its motion is measured?
Work is force X distance travelled. Force is mass x acceleration. Aceeleration depends on the frame of reference from which one is measuring it. Hence work done depend on the frame of reference from which one is measuring it. QED
Does the work done by the net force acting on a particle depend on the inertial reference frame of the observer.does the change in kinetic energy so dependent if so?
No, the work done by the net force on a particle is independent of the inertial reference frame of the observer. However, the change in kinetic energy is frame-dependent due to the kinetic energy term in the relativistic energy equation.
Total kinetic energy of zero?
Anything that's standing still (within the frame of reference).
You watch your friend take off in a jet plane and you comment on the kinetic energy she has acquired But she says she has no such increaze in kinetic energy Who is correct?
You are correct. When the jet moved, she moved with it. If she was moving faster than she was before, then she gained kinetic energy. She lost that kinetic energy when the plane touched down and came to a stop.
A Plane flying past a non-moving observer has kinetic energy in the reference frame of this observer the same plane has how much kinetic energy in the reference frame which moves with the plane?
Zero. I am currently sitting in my chair in my room. If the plane is my chair and my room is the reference plane as long as I don't move my chair around the room it has no kinetic energy. Now if I expand my reference plane to an observer on the sun (I know) they are going to see me and my chair hauling butt at about 30km/s around the solar system along with my room my house and the rest of the planet this velocity and my mass mean there is kinetic energy.

Does everyhting have energy?
Basically yes. There are different types of energy; for example: * Kinetic energy: Every moving object has kinetic energy. Whether an object is moving or not depends on the reference frame you choose. * Gravitational potential energy: Once again, you need to choose a reference point - or actually, a reference height in this case. Anything above the chosen reference height will have positive potential energy; anything below it, negative potential energy. * Heat energy: Since you can't cool any object to absolute zero, any object will have at least some heat energy.
Energy can be formally defined as?
Energy can be formally defined as the ability to do work or cause change in a system. It exists in various forms, such as kinetic, potential, thermal, and chemical energy. The total energy in a closed system remains constant according to the law of conservation of energy.

Does the inside of a plane have Kinetic Energy?
Each mass object in there has.That's why it's harder to take off when the plane is full ... the engines have to pump all that kinetic energyinto every suitcase and body inside.
