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 work done equation?

Scientifically Work done formula will be given as, W = F * d: In this case, the force exerting on the block is constant, but the direction of force and direction of displacement influenced by this force is different.

## How do you calculate work energy?

Key Points

- The work W done by the net force on a particle equals the change in the particle’s kinetic energy KE: W=ΔKE=12mv2f−12mv2i W = Δ KE = 1 2 mv f 2 − 1 2 mv i 2.
- The work-energy theorem can be derived from Newton’s second law.
- Work transfers energy from one place to another or one form to another.

## What is current formula?

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

## What are the 3 version of work formula?

There are three key ingredients to work – force, displacement, and cause.

## What is normal force formula?

In this simple case of an object sitting on a horizontal surface, the normal force will be equal to the force of gravity F n = m g F_n=mg Fn=mgF, start subscript, n, end subscript, equals, m, g.

## 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.

## How do you calculate total current?

What is the formula for a total current? IT = VT/RT or I total = V total / R total or the total current = the total voltage / the total resistance.

## What is SI unit current?

Unit of electric current: ampere (A) The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10^{−}^{19} when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆ν_{Cs}.

## 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.
