## How to calculate your daily energy expenditure? The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.

## How do you calculate energy in physics?

• Know the formula for calculating kinetic energy. The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2. Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position.

## What are 5 sources of electricity?

• 1) Solar Energy. 2) Wind Energy. 3) Geothermal Energy. 4) Hydrogen Energy. 5) Tidal Energy. 6) Wave Energy. 7) Hydroelectric Energy. 8) Biomass Energy. 9) Nuclear Power. 10) Fossil Fuels (Coal, Oil and Natural Gas)

## How do you calculate kinetic and potential energy?

• The equation for calculating kinetic energy is KE = ½mv², where m is the mass of the object and v is its velocity. When an object is at its highest, it has the most potential or stored energy; at its lowest point, it has its most kinetic energy.
