When a boy kicks a football, the mechanical energy from his leg muscles is transferred to the football, causing it to move. Some of this energy is converted into kinetic energy as the football gains velocity, while other energy is converted into sound and heat energy due to friction with the ground and air resistance.
When a football is kicked upward, the main energy transfer occurring is from the kicker's leg muscles to the football. This transfer involves potential energy being converted to kinetic energy as the football gains height due to the force of the kick. Gravitational potential energy is also a factor as the football gains altitude.
The object's potential energy decreases as it moves to a lower place due to a change in its position in the gravitational field. This decrease in potential energy is often converted into kinetic energy as the object accelerates downward.
The changes of state that involve losing energy are condensation (gas to liquid), freezing (liquid to solid), and deposition (gas to solid). These changes require the release of energy, typically in the form of heat, to facilitate the transition.
When a candle burns, the chemical potential energy stored in the wax is converted into heat and light energy through the process of combustion. The heat energy generated causes the surrounding air to warm up, while the light energy is emitted as a visible flame.
During the generation of electricity, energy changes occur as different forms of energy are converted. Typically, the process involves converting mechanical energy (e.g. from spinning turbines) or chemical energy (e.g. from burning fuels) into electrical energy through generators or other systems. Heat energy may also be produced as a byproduct of these energy conversions.

Kinetic Energy takes place, due to the fact you apply energy to the scissors.

Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Spread betting allows one to place a bet on such aspects as the number of total goals, the aggregate of the goal scorers shirt numbers, the number of corner kicks taken or even the timing of the goals.
