In physics, the kinetic energy (KE) of an object is the energy that it has due to its motion. It is defined as the work needed for an object of a known mass to accelerate to a given velocity. This energy the object gains during its acceleration, will be maintained unless its speed changes.

Specific heat capacity is how much heat energy is required to raise 1 kg of a substance by 1 °C.
…
The quantity power is the rate at which work is done. The quicker work is done the greater the power.
…
Stretching or squashing an object can transfer energy into its elastic potential energy store.
…
The size of the current is the rate of flow of charge. Electrons are negatively charged particles which transfer energy through wires as electricity
…
Resistance is an electrical quantity that measures how a device or material reduces the electrical current flow through it
…
Resistors in series and in parallel can change the total resistance in a circuit
…
The power of an appliance is the energy that is transferred per second. Electric power is the rate, per unit time at which electrical energy is transferred by an electric circuit
…
Density is a measure of how compact the particles are in a substance. Density is defined as the mass per unit volume.
…
Specific latent heat is the energy needed to change the state of a substance.
