There are three energy systems: the immediate energy system, the glycolytic system, and the oxidative system. All three systems work simultaneously to a degree, but parts of the system will become predominant depending on what the needs of the body are.

Heat can be transferred in three ways: by conduction, by convection, and by radiation.

• Conduction is the transfer of energy from one molecule to another by direct contact.
• Convection is the movement of heat by a fluid such as water or air.
• Radiation is the transfer of heat by electromagnetic waves.

Whenever there is a change in a system, energy is transferred and some of that energy is dissipated . Dissipation is a term that is often used to describe ways in which energy is wasted. Any energy that is not transferred to useful energy stores is said to be wasted because it is lost to the surroundings.

The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. This is used across different methods of measuring energy and work, whether it’s energy production or machine efficiency.

efficiency = (10 + 20)% = 30%. This means in one day A and B together can do 30% of the work. Therefore, Number of days A and B together take to do 100% of work = (100/3) days = 3.33 days. Example 3: A can do a certain work in 12 days.

The bounce efficiency of a tennis ball is calculated by using the two heights of the ball, one, at the max height of the ball before the bounce, and second, after the bounce. Using the gravitational potential energy at both heights one can identify the bounce efficiency.

If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.

This elastic potential energy is why the ball is able to bounce, or rebound. After the ball rebounds, the elastic potential energy is transformed into kinetic energy, but it will never possess as much kinetic energy as during its original fall. The ball will never be able to rebound to its original height.

The force of the ball hitting the hard ground puts an equal force back onto the ball, meaning it bounces back up. This happens because balls are made out of an elastic material which allows them to be squashed or stretched and then return to their original shape.

Boiling water on a stove is an example of thermal energy. Thermal energy is produced when the atoms and molecules in a substance vibrate faster due to a rise in temperature.

Heat transferred from an electric stove to the bottom of a pot is an example of conduction. Some materials conduct thermal energy faster than others. For example, the pillow in your room may the same temperature as the metal doorknob, but the doorknob feels cooler to the touch.

Thermal energy is the energy that is generated and measured by heat. An example of thermal energy is the kinetic energy of an atom.

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth’s surface is in two forms, visible and infrared light. This transfer of energy can take place by three processes: radiation, conduction, and convection.

This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.

In the case of thermal radiation from a solid surface, the medium through which the radiation passes could be vacuum, gas, or liquid. Molecules and atoms of the medium can absorb, reflect, or transmit the radiation energy.

The energy associated with a single photon is given by E = h ν , where E is the energy (SI units of J), h is Planck’s constant (h = 6.626 x 10–34 J s), and ν is the frequency of the radiation (SI units of s–1 or Hertz, Hz) (see figure below).
