Equation for work done
What is the formula for 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 Joules |
What is the formula and unit for work?
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 work done in physics?
In summary, work is done when a force acts upon an object to cause a displacement. Three quantities must be known in order to calculate the amount of work. Those three quantities are force, displacement and the angle between the force and the displacement.
What is the unit of work done?
One joule
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’s the formula for charge?
How is Electric Charge Measured?
| Definition | The physical properties of matter which allows it to experience a special kind of force when kept under the influence of the electromagnetic field is called Electric Charge |
|---|---|
| Symbol | Q |
| Formula | Q = I.t |
| SI unit | Coulomb |
| Other units | Elementary charge |
What is the formula for time?
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
What is the SI unit of force?
The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.
What is the efficiency formula?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
What is no work is done?
If there is no motion in the direction of the force, then no work is done by that force.
What is work equal to 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.
Which is not unit of work?
Volt
What is the formula of work and energy?
