# Quick Answer: How To Find Work In Physics?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

## What is the formula of work done?

Mathematically, the concept of work done W equals the force f times the distance (d), that is W = f. d and if the force is exerted at an angle θ to the displacement, then work done is calculated as W = f.

## How do you find work Physics with time?

Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W. You can also use our power calculator to find work – simply insert the values of power and time.

## What is current formula?

The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).

## What’s the best way to find a job?

Best ways to find a job

1. Ask your network for referrals. If you are looking for a job, you should tell all your contacts to help them help you find mutual career contacts.
2. Contact companies directly.
3. Use job search platforms.
4. Go to job fairs.
5. Leverage social media.
6. Inquire at staffing agencies.

## What is current unit?

The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp. Meanwhile, the formula for electric current is given as follows: I = V/R.

## What is Ohm’s law state?

Ohm’s law states that the current through a conductor is proportional to the voltage across the conductor. V=IR where V is the voltage across the conductor and I is the current flowing through it.

## What is resistivity formula?

Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. The unit of resistance is the ohm.

## What is formula of mass?

Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as: Mass = Density × Volume.

## What is formula of stress?

stress = (elastic modulus) × strain.

## What is E mc2 used for?

E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other.
