Does kinetic energy always convert back into gravitational potential energy?

If you stood at the top of a building with a bottle rocket and aimed it straight at the ground and fired it, it's kinetic energy would exceed it's initial gravitational potential energy. It's kinetic energy would equal the acceleration due to gravity plus the energy of the rocket thrust minus any resistance to air as a result of it's shape.

∙ 12y agoyes, in fact potential energy is zero when kinetic energy is at its maximum, however kinetic energy and potential energy together will always equal the total energy. Therefore kinetic energy will equal total energy-potential energy and potential energy will equal total energy-kinetic energy

∙ 11y agoNo, motion doesn't always go vertically (up and down). Gravitational Potential Energy isdependenton height, but if an object is just moving horizontally, than it is not gaining any height, and therefore it is not gaining any potential energy.
Kinetic energy is more likely to be converted to heat, by means of friction than anything else. Friction "steals" from the kinetic energy.

Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.
Is potential energy was converted to kinetic energy?
It CAN be converted to kinetic energy, but it won't always do so.
How does a yo yo transfer both potential and kinetic energy?
The yoyo is a good example of how potential and kinetic energy can oscillate. When fully up and stationary it has zero kinetic and only potential, when it is fully down and rotating at max speed this energy has been converted to kinetic, then it climbs up again, and so on. The player has to keep providing a small input of energy to overcome friction losses.
A ball thrown by a boy from the roof top is what motion?
When the boy is holding the ball it has Gravitational Potential Energy (GPE).When he lets go the Gravitational Potential Energy is converted to Kinetic Energy.As the ball is falling it continues to gain Kinetic Energy, however, the friction from the air on the ball increases (Air Resistance).When the Kinetic Energy and Air Resistance become equal the ball is said to have to reached Terminal Velocity.Once the ball hits the ground the Kinetic Energy is transferred to the ground through heat (Friction) and also as sound.Remember energy cannot be created or destroyed, it is always transferred.
What is the sum of kinetic energy and potential energy in a closed system?
Always remains the same.

Does an object with high gravitational potential energy always have a low kinetic energy?
No. For example, a satellite in orbit has a lot of both.
What does gravitational potentail energy mean?
Technically gravity is always working so it cannot be potential, I would say that if anything it is kinetic. The influence that gravity has on everything gives that object potential energy.
Why is gravitational potential renewable?
It is renewable because you can always raise an object or raise yourself and gain gravitational potential energy. You cannot run out of gravitational potential energy and even now you have some of the the energy because gravity is always pulling you. It is just a matter of how much gravitational potential energy you have. Go on the top Mt. Everest and you will have more gravitational potential energy than most of the people in the world.
