NCERT solutions for class 11 Physics and NCERT solutions for class 12 Physics. When the distance covered by the body is 5m, its kinetic energy would beįinal kinetic energy = Initial energy – work done against resistive force (Area between graph and displacement axis)įor More Physics formulas vist main page and do solve exercise of NCERT from Physics Wallah. The mass of the body is 25 kg and initial velocity is 2 m/s. Problem 3: The graph between the resistive force F acting on a body and the distance covered by the body is shown in the figure. Work done = Covered area on force-displacement graph = 1 × 10 + 1 × 20 -1 × 20 + 1 × 10 = 20 erg.
#WORK DONE PHYSICS CALCULATOR FULL#
It helps you practice by showing you the full working (step by step differentiation). The work done by the force in displacing a body from x – 1 cm to x – 5 cm is Our calculator allows you to check your solutions to calculus exercises.
#WORK DONE PHYSICS CALCULATOR HOW TO#
If you dont know how to calculate work, use this total work. Problem 2: The relationship between force and position is shown in the figure given (in one dimensional case). Use work calculator (physics) to find work done with force & displacement or velocity change. Work done on the mass = mass × covered area between the graph and displacement axis on a-t graph. What is the total work done on the mass by the force as the mass moves from x = 0 to x = 8 cm DC power calculator AC power calculator Energy &. Its acceleration as a function of its position is shown in the figure. Power consumption calculator: calculates electric power / voltage / current / resistance. Problem 1: A 10 kg mass moves along x-axis. W = Area under curve between x i and x f i.e Area under force displacement curve with proper algebraic sign represents work done by the force.ĭisplacement Equations for these Calculations:ĭifferent resources always use slightly different variables so you might also encounter this same equation with vi or v0 representing initial velocity (u) and vf representing final velocity (v) given below:Įxamples For Work Done Calculation by Force Displacement Graph The work done on the body in displacing it from position x t to x f will be qual to the sum of areas of all the such strips The work done will be the area of the shaded strip of width dx. Let be the average value of variable force within the interval dx from position x to (x +dx) i.e. Let a body, whose initial position is x t, is acted upon by a variable force (whose magnitude is changing continuously) and consequently the body acquires its final position x f. Work Done Calculation by Force Displacement Graph How do you calculate work performed for events in zero G In middle school we all learn that work equals force multiplied by displacement. This video is meant for students studying in class 9 and 10 in CBSE/NCERT and other state boards.Abo. (HINT: Be cautious with the units.) See Answer 9. In the more general cases where everything varies, one often calculates the work first and then divides by the time to get the average power.Formula For Work Done Calculation by Force Displacement Graph Physics Formulas This Physics video explains how to calculate work done. Calculate the work done by a 2.0-N force (directed at a 30 angle to the vertical) to move a 500 gram box a horizontal distance of 400 cm across a rough floor at a constant speed of 0.5 m/s. Then for instantaneous power, you just multiply the product of force and velocity by the cosine of the angle between them to get the power. This calculation is only for cases where the force is in the direction of the velocity, and there are many cases where that is not so. A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts.
The rate of doing work is equal to the rate of using energy since the a force transfers one unit of energy when it does one unit of work. The standard unit for power is the watt (abbreviated W) which is a joule per second. In a more general case where the velocity is not in the same direction as the force, then the scalar product of force and velocity must be used.
In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv.
It can calculate current, voltage, resistance, work, power and time depending on what variables are known and what are unknown You can use this online calculator to check the solution of problems for electric power and electrical work.
Often it is convenient to calculate the average power. This online calculator can help you solve the problems on work done by the current and electric power. These two definitions are equivalent since one unit of energy must be used to do one unit of work. Power PowerPower may be defined as the rate of doing work or the rate of using energy.
