## 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**.
