To find: Work done by the force in moving the object through a distance of 7 m So the displacement of the bag in the direction of the force (weight) is zero.Īnswer: Work done by the coolie on the bag is zero.Įxample 3: Calculate the amount of work done by the force in moving the object through a distance of 7 m if an object is horizontally dragged across the surface by a 150 N force acting parallel to the surface. Calculate the work done by the coolie on the bag by using the formula for work.Īlso, the weight of the bag will be acting in the vertical direction and its motion is in the horizontal direction. Calculate the work done by using the formula for work.Īnswer: 20 Nm of work is done when a 10 Newton of force displaces an object by 2 meters.Įxample 2: A coolie at a railway station carries a bag weighing 100 N through some distance.

With Cuemath, find solutions in simple and easy steps.īook a Free Trial Class Examples Using Formula For WorkĮxample 1: 10 Newton of force is applied on a body which displaces it by 2 meters. Use our free online calculator to solve challenging questions. Now, if the effective component of force along the direction of displacement is Fcosθ responsible for the displacement of any object in the given direction, then work done by the force F in displacing the body through displacement d is, W=(|F|cosθ)|d| Since F = ma (Newton's 2nd law), thus W = Fs. In general, the work done by force F is equal to the change in kinetic energy If 1 joule of work is done then the formula for work comes out to be 1 J = 1 N.m Derivation of Work FormulaĬonsider 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.
The formula for work is used to calculate work done in moving an object. If the displacement in the direction of force is zero then the work done becomes zero. The server has its own IP, which receives your internet traffic. Proxy servers act as intermediaries or gateways between you and the internet. Work is said to be done when we apply a force on an object and the object experiences displacement. Before the widespread introduction of VPNs, proxy servers stood as the main way for internet users to hide their IP addresses and stay safer online. Before we learn the formula, let us recall what work means. The formula for work is used to calculate the work.
