2. Power (physics)

Alpha decay

Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or "decays" into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.

See Power density and Alpha decay

Energy density

In physics, energy density is the amount of energy stored in a given system or region of space per unit volume.

See Power density and Energy density

Lithium-ion battery

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy.

See Power density and Lithium-ion battery

Metre

The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI).

See Power density and Metre

Plutonium

Plutonium is a chemical element; it has symbol Pu and atomic number 94.

See Power density and Plutonium

Power (physics)

Power is the amount of energy transferred or converted per unit time.

See Power density and Power (physics)

Power-to-weight ratio

Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power density and power-to-weight ratio are power (physics).

See Power density and Power-to-weight ratio

Specific absorption rate

Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field.

See Power density and Specific absorption rate

Specific energy

Specific energy or massic energy is energy per unit mass.

See Power density and Specific energy

Supercapacitor

doi-access.

See Power density and Supercapacitor

Surface power density

In physics and engineering, surface power density is power per unit area.

See Power density and Surface power density

Volume

Volume is a measure of regions in three-dimensional space.

See Power density and Volume

Watt

The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3.

See Power density and Watt
