The definition of work done is given by the product of force ( ) and the distance moved in the direction of force ( ). The unit of work done is in Joules (J), which is equivalent to Newton metres (Nm). Example 1: A van is driven along a straight horizontal road.
Force-Distance graphs If the force is non-uniform then the formula W = F × d does not apply. Instead, we present the information as a force-distance graph and calculate the area beneath the graph to find the work done by the force. Recall the other “area under a graph”, which is the force-time graph that gives the impulse of a force.
Work done is simply just the transfer of energy from one object to another. We say that work is done on an object when a force causes it to move a particular distance. To calculate the work done by a force 𝐹𝐹 on an object: 𝑊𝑊𝑊𝑊𝑊𝑊𝑊𝑊 𝐷𝐷𝑊𝑊𝐷𝐷𝐷𝐷=
Work = Force X Distance Work = 20N X 10m Work = 200 J. 2) How much work does an elephant do while moving a circus wagon 20 meters with a pulling force of 200N?
Work is application of force, f f, to move an object over a distance, d, in the direction that the force is applied. Work, W , is described by the equation W = f d .
PHYS 1301 Equation Sheet 1 Vectors Work, Energy, and Power Equations ⃗= ë ̂+ ì ̂ =√ ë2+ ì2 = 𝜃 (for constant force) sin𝜃= ℎ , cos𝜃= 𝑎 ℎ , tan𝜃= 𝑎 = 1 2 v2 (for linear motion)
Work = Force X Distance. W = F d. The units of force are Newtons and the units of distance are meters. The answer is in Newton-Meters. These units are referred to as Joules. Work Problems. 1. A force of 800 Newtons is needed to push a car across a lot. Two students push the car 40 meters.
