In the case of a variable force, integration is necessary to calculate the work. To calculate the work done. Work = force × distance.

Where, f is the force applied;
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.
The equation for work is. Work done = force × distance. The following diagram gives the formula for work done by a force. Scroll down the page for more examples and solutions on how to use the formula.
The general formula for work and for determining the amount of work.
Action of this force is to move the body through a distance d in a straight line in the direction of force. For more physics formulas vist main page and do solve exercise of ncert from entrancei ncert solutions for class 11 physics and ncert solutions for class 12 physics. W = f ⃗ ∙ d ⃗. The amount of work done upon an object depends upon the amount of force (f) causing the work, the displacement (d) experienced by the object during the work, and the angle (theta) between the force and the displacement vectors.
Θ is the angle between force and direction of motion;
When an object moves a distance δ x along a straight line as a result of action of a constant force f, the work done by the force is \[w = f\delta x.\] this equation is called the constant force formula for work. In physics, we say that a force does work if the application of the force displaces an object in the direction of the force. Now , work done by this force is equal to the product of the magnitude of applied force and the distance through which the body moves. Here, force f reacts at an angle θ to the displacement d.
But, isn't this contrary to the fact that work is a conservative force.
Work done is measured in joules (j) force is measured in newtons (n) distance moved along the line of action of the force is measured in metres (m) W f e = 1 2 k ( x 0 2 − x 2); If that force is constant then the work done by the force is the dot product of the force with the displacement: If 1 joule of work is done then the formula for work comes out to be 1 j = 1 n.m.
W f e = − 1 2 k x 2 for both cases where the spring is compressed and stretched.
Scientifically work done formula will be given as, w = f * d. Work can be calculated with the equation: Examples for work done calculation by force displacement graph. W=\vec {f} \bullet \vec {d}.
Your approach is correct, it will lead to the right answer.
It is articulated in nm. In such a case, work (w) is equal to the force applied (f) multiplied by displacement (. Formula for work done calculation by force displacement graph. Work is done whenever energy is transferred from one store to another.
Si unit of work is joule (j).
W = f⋅δx w = f ⋅ δ x. The general formula of the work is: W = (|f| cosθ) |d|. Electrical work involves a current transferring.
Work done by a force can be divided into work from a constant force and work from a variable force.
The amount of work a force does is directly proportional to how far that force moves an object. F ( x, y) = ( x y, 3 y 2) r ( t) = ( 11 t 4, t 3) r ′ ( t) = ( 44 t 3, 3 t 2) ∫ 0 1 f ( r ( t)) ⋅ r ′ ( t) d t = ∫ 0 1 ( 11 t 4 ∗ t 3, 3 t 6) ⋅ ( 44 t 3, 3 t 2) d t = ∫ 0 1 484 t 10 + 9 t 8 d t = 44 t 11 + t 9 | 0 1 = 45. W = f ∙ d. The work done by the frictional force is as follows.
In the former kind, the magnitude and direction of the force remain unaltered.
On an object when a force moves it, use the equation: Mechanical work involves using a force to move an object. $$e = \frac {1} {2}kx^2 $$. Work formula is made use of to compute work done, force, or displacement in any problem.
The formula for calculating the elastic potential energy of a spring is:
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. I have a doubt about the work done by elastic force. Equation for calculate work done by frictional force is, work done by frictional force = frictional force * distance moved work done by frictional force calculator Work done = force × distance \[w = f~s\] this is when:
The net work done on an object (the work of the net force) is equal to the energy added to the object.
Work done (w) is measured in joules (j) In other words, work is equivalent to the application of a force over a distance. The work formula is articulated as. One joule equals the amount of work that is done when 1 n of force moves an object over a distance of 1 m.
Work done by driving force = change in k.e + change in p.e + workdone against resistance.
Work done by a force. Since resistance is a force which opposes motion, the work done against any resistive forces must be subtracted from the work/energy equation. If we take that the state in which the spring is at rest, we have: The si unit for work is the joule (j), or newton • meter (n • m).
