Net Force to Work Formula:
The concept of work in physics is central to understanding energy transfer in systems. Work (W) is defined as the force applied to an object multiplied by the distance over which the force is applied, and in the direction of the force.
This relationship is crucial in mechanics, where it helps describe how much energy is transferred by a force moving an object over some distance.
The formula to calculate work is based on the net force applied to an object and the distance the object travels while the force is applied.
Net force (NF) is the total force acting on an object, considering all the acting forces are vectorially added. Distance (D) is the displacement of the object in the direction of the net force.
Work, W(N-m) Newton metres is calculated by the product of Net force, NF(N) in Newtons and distance, D(m) in metres.
Work, W(N-m) = NF(N) * D(m)
W(N-m) = work in Newtons metres, N-m.
NF(N) = net force in Newtons, N.
D(m) = distance in metres, m.
Net Force to Work Calculatiion:
1.Calculate the work done by a tugboat:
Given: NF(N)= 2000 N, D(m)= 100 metres
Work, W(N-m) = NF(N) * D(m)
W(N-m) = 2000 * 100
W(N-m) = 200,000N-m.
2.Suppose the net force applied to an object is 800 newtons, and the work done is 4000 N-m.
Given: NF(N)= 800N, W(N-m) = 4000N-m.
Work, W(N-m) = NF(N) * D(m)
D(m) = W(N-m) / NF(N)
D(m) = 4000/800
D(m) = 5m.
