## What is the formula for energy?

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..

## What is E mc2 used for?

E=mc2 explains why the sun and other stars shine. In their interiors, atoms (mass) fuse together, creating the tremendous energy of the sun as described by Einstein’s famous equation. Albert Einstein in 1905, his “miracle year.” Image via Wikimedia Commons.

## What is the current formula?

Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.

## What is the 5 rule in physics?

The purpose of the 5% Rule is to give you the option of eliminating a vertical axis intercept. When you have a vertical axis intercept that you believe exists only because of error in your data, the 5% Rule can be invoked (if all conditions are met) and the intercept may be dropped from you mathematical equation.

## What is power formula?

or. P = W / t. The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second.

## How do you convert joules to KG?

Please provide values below to convert joule [J] to kilogram-force meter, or vice versa….Joule to Kilogram-force Meter Conversion Table.Joule [J]Kilogram-force Meter1 J0.1019716213 kilogram-force meter2 J0.2039432426 kilogram-force meter3 J0.3059148639 kilogram-force meter5 J0.5098581065 kilogram-force meter7 more rows

## How do you convert N to joules?

One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

## What is the formula of work and energy?

What is Work, Energy and Power?WorkFormulaWe can calculate work by multiplying the force by the movement of the object. W = F × dUnitThe SI unit of work is the joule (J)Energy8 more rows

## How do I calculate unit?

Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).

## What is the unit of current *?

ampereThe SI unit of electric current is the ampere, or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.

## What is the formula of work done?

One can calculate the work done by an airplane by using the equation: W = F x D For instance, if a model airplane exerts 0.25 Newtons over a distance of 10 meters, the plane will expend 2.5 Joules.Work= F x D= 0.25 * 10= 2.5 Joules1 more row
