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 in physics?
To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
How do you find the equation for work?
The formula for work is, work equals force times distance. In this case, there is only one force acting upon the object: the force due to gravity. Plug in our given information for the distance to solve for the work done by gravity. Remember, since the object will be moving downward, the distance should be negative.
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 formulas for work?
- Work = Force • Displacement • Cosine(theta)
- W = F • d • cos(theta)
- Power = Work / time.
- P = W / t.
- P = F • cos(theta) • (d/t)
- P = F • v • cos(theta)
- PEgrav = m•g•h.
- KE = 0.5 • m • v2
What is formula for mass?
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass. The SI unit of mass is “kilogram”.
What is the formula of time?
FAQs on Time Formula The formula for time is given as [Time = Distance ÷ Speed].
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.
How do I calculate power?
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 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 the D in work formula?
What Is d in Work Formula? In the work formula W = F. d, d is the displacement as in how much the object has moved from its initial place.
What is the formula of time and work?
Important Time and Work Formula Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.
