Kinetic energy - the energy of a mass in motion CAN be greater than the potential energy of the mass.

The kinetic energy of a comet hitting the Earth would be far greater than the potential energy of the comet once it entered Earth gravity field.

What energy can change from on form to another but cant be created or destroyed?

The energy that can change from one form to another but cannot be created or destroyed is known as "energy conservation." According to the law of conservation of energy, the total energy in a closed system remains constant over time, even as it may change forms such as kinetic, potential, thermal, or chemical energy.


What some examples of kinetic and potential energy?

Any fluid/object in motion possesses Kinetic energy. Energy stored in an object/fluid due to its height is known as Potential energy. Water stored up in dam has potential energy and when it is allowed to flow downhill it possesses kinetic energy. Pendulum is also a good example to demonstrate both kinetic and potential energy. The total quantum of energy in this universe remains constant.


What is gravitational energy-?

Gravitational potential energy is the kinetic energy that an object could gain if it was allowed to move through the entire gravitational potential in question. For example, if you climb a tower that is 100 feet above the Earth's surface and hold a ball, the ball will have potential energy as long as it remains at that height (in other words, as long as it remains at that potential). If the ball is dropped, the potential energy begins converting into kinetic as the ball falls through the 100 foot gravitational potential. When the ball is on the surface of the Earth, it no longer has any gravitational potential energy with respect to the Earth's surface. All of the energy converted into kinetic energy. When the ball actually hit the Earth, the kinetic energy was converted into heat and the ball stopped moving. That heat warmed the surrounding atmosphere a bit. No energy is ever lost, it just converts from one form to another.


Is potential energy the same as energy being conserved?

Not really... Kinda? Potential energy is the total possible energy based on position. Ex: A rock on the floor will have less potential energy (since it's on the floor and it wont have energy since it's not moving), than a rock 100 meters in the air. (More potential energy since it will falling). Or a rubber band being pulled back has more potential energy than when its not pulled. Conserve means to save/store, and things cant really "store" energy.


What types of energy are used when blowing a whistle?

there is a little energy used, the point is you simply convert a wind energy into a sound energy. remember you cant create any kind of energy.

How can you find kinetic energy?

Heat is just the measure of the average kinetic energy of the molecules in... whatever you are measuring. Kinetic energy is s form of energy, so the fact that the molecules have kinetic energy proves heat is energy. Also heat powered engines do work by converting heat into kinetic energy. ============================ Thanks for that. But how do you prove that heat is a form of energy ? ============================


Why cant the kinetic energy of all the atoms in an object be measured?

because they are so small and objects contain so many of them, it is impossible to measure the kinetic energy of all the individual atoms


What is is potential energy stored in?

Potential enery depends only on the position of the object. It cant be 'stored'.


How can energy be stored?

Energy can be stored in various forms such as chemical energy in batteries, potential energy in elevated objects, kinetic energy in moving objects, thermal energy in hot materials, and gravitational potential energy in raised weights. Different storage methods suit different energy needs and applications.


How does kinetic energy affect your life?

Kinetic energy is the energy an object possesses due to its motion. In daily life, kinetic energy plays a role in activities such as walking, driving a car, or playing sports. Understanding kinetic energy helps in calculating the speed and impact of moving objects, which is important for safety in various situations.

What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?

Firstly, momentum is not a form of energy; the question seems to imply so. Kinetic energy is the energy possessed by a moving object. That energy is provided by a source, and can be removed from the object because energy possessed by an object is not an inherent part of that given object. Momentum is a property of mass; momentum is inherent in the mass of the object, and cannot be removed or put somewhere else, only altered.
