equation for work

How do you find the work equation?
It is directly related to both the force applied to the object and the distance the object moves.
Work can be calculated with this equation when force and the distance moved are in the same direction: Work = Force x Distance._{6 fév. 2023}
What is the general work equation?
To calculate work done by a constant force, we can use the following general equation: work = force × displacement ‍ .
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.

What are the 3 formulas for work?

The work W that a force F does on an object is the product of the magnitude F of the force, times the magnitude d of the displacement, times the cosine of the angle θ between them.
In symbols, W = Fd cos θ.
The SI unit for work and energy is the joule (J), where 1 J = 1 N ⋅ m = 1 kg ⋅ m²/s².

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.

What Is Formula For Work?

The formula for work is used to calculate the work done to displace any object. Work is the product of the force applied and displacement in the direction of the force applied. Work is the dot product of the two vectors: force and displacement. Thus work is a scalar quantity. SI unit of work is Joule (J). cuemath.com

Derivation of Work Formula

Consider a block placed on a frictionless horizontal floor acted upon by a constant force F due to which this block moves through a distance d in a straight line in the direction of the force. In general, the work done by force F is equal to the change in kinetic energy W = (1/2)mv2 - (1/2) mu2 = 1/2m(v2-u2) Applying v2-u2= 2as W = (1/2)m(2as) W =

Examples Using Formula For Work

Example 1: 10 Newton of force is applied on a body which displaces it by 2 meters. Calculate the work done by using the formula for work. Solution: To find: Work done Given: Force (F) = 10N Displacement (d) = 2 m Using Formula For Work, W = F.d = (10)(2) = 20Nm Answer: 20 Nm of work is done when a 10 Newton of force displaces an object by 2 meters
