![]() Tension is a force that works in medium lengths, especially those that are flexible, such as rope or cord. The direction of this force corresponds to the length of the cord. At the ends, the cord will apply pressure to the object connected to it (the force of gravity), and the object will use the reaction force of the rope towards it. So in any cross-section, we can see tension forces working on both sides. Similarly, the second part of the cable uses the reaction power of the first part. ![]() If we consider any cross-linking, the part of the string on one side to the cross-section will use the force of action on the part of the string on the other side in the cross-section. Often referred to as the power of the "action-reaction pair", the tension applies to each component of the adaptive object. Tension force is the force of contact which is carried with a flexible medium length. The force or power based on how it works and transmits can be the ability to contact or non-contact. In physics, we are dealt with several types of forces like weight, normal force, push, collision, etc. We know that a push or pull is indicated by a tension force. The force which is applied to the length of a flexible area such as a rope or a cable, or chain is referred to as tension formula force in physics. In Latin, the word "tension" means "stretching". Θ = 0, Īnswer: The amount of work done by the force in moving the object is 800 J.Tension refers to the pulling force transmitted axially by the means of a string, cable, chain, or similar one-dimensional continuous object, or by each end of a rod, or similar three-dimensional object tension might also be described as the action-reaction pair of forces acting at each end of the said elements. 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. ![]() θ = is the angle between the vectors: force and displacement.d = Magnitude of the displacement in the direction of the force.The formula for Work can be expressed as, Work is the dot product of the two vectors: force and displacement. 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. Let us learn more about the formula for work along with solved examples in the following section. 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. Work is said to be done when we apply a force on an object and the object experiences displacement. Before we learn the formula, let us recall what work means. The formula for work is used to calculate the work.
