What type of energy is it when a ball hits the ground?
it's still kinetic energy when it's in the air, MOVING, that's what kinetic energy is. But before it falls, let's say it's on the top of a hill or in someone's hand, it has potential energy.
Can an object gain more energy?
Sure, you can add energy to an object. For example, you can heat an object up (to have it gain heat energy), you can raise it (to have it gain gravitational potential energy), or you can make it move (to have it gain kinetic energy). In each case, the energy has to come from somewhere.
When you throw a ball in the air what type of energy does it gain as it rises?
When the ball leave your hand it goes up with an initial velocity v0 so that the action of your hand gives the ball the kinetic energy K=0.5 M v02 where M is the ball mass. When the ball goes up the kinetic energy decreases: a part is converted in potential energy while the balls is higher and higher and part is dissipates due to the attrition with air (that more precisely is due to air viscosity) and to the fact that air particles are put in motion by the arrival of the ball so that they gain kinetic energy at the expenses of the kinetic energy of the ball due to collision. Neglecting the last term that, due to the small density of air with respect to the ball is generally quite small, the viscosity dissipate energy mainly by generating heat. When the ball stops at maximum height the kinetic energy is reduced to zero (the velocity is zero) and all the energy is potential, while a certain amount of heat has been dissipated during the motion. If we call Q the quantity of generated heat and h the maximum height reached by the ball, for the energy conservation rule we have 0.5 M v02=Q+M g h If the air viscosity is negligible, or if the ball goes up in vacuum, Q is zero and we can deduce the maximum height the ball reaches h=(M v02)/( 2 M g)
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.
How do objects gain energy?
An object can gain kinetic energy by accelerating or gravitic energy by increasing height, among other things.
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.
How do foxes gain energy?
They gain energy by eating food.

Why does it make more energy to stop a moving ball than the energy required to keep it moving?
The natural tendency of a moving object is to keep moving. And it doesn't really require energy to stop it; in fact, in theory, you can gain energy from it. What is required is a force.

Do objects gain energy when they are hot?
No, objects that gain energy become hotter.

How volcanoes gain more energy?
Volcanoes gain energy from the hot magma inside it
NFL Possession while in the air?
By definition, a ball "in the air" is a loose ball, and therefore no one has possession. However, depending upon the circumstances, it's possible that only one team has the right to gain possession (for example, a punted ball).
Do hurricanes gain energy?
Yes. Hurricanes gain energy from moisture that evaporates from warm ocean water. A hurricane could never develop if it were unable to gain energy.
