5 Find the horizontal component using trigonometry, it is 2cos(30 degrees) = sqrt(3) newtons. This calculator will find the missing variable in the physics equation for Work, when two of the variables are known. In general, the formula for the kinetic energy of an object is:Donkey and Diddy Kong are sitting in a 90-kilogram minecart that is initially traveling horizontally at a velocity of 5 m/s. ≤ The formula used in the compound interest calculator is A = P(1+r/n) (nt) A = the future value of the investment; P = the principal investment amount; r = the interest rate (decimal) n = the number of times that interest is compounded per period; t = … The initial kinetic energy of the car is:Since we know the total amount of work done on the system (60000 J) we can figure out the car’s final kinetic energy:Now, since we know the final kinetic energy and the mass of the car, we can determine its final velocity like thisSo in summation, we say work is done whenever a force moves an object over a distance. For the first part of her trip, she exerts 300 N of force to move a suitcase 16 meters vertically so the amount of work done is:So the first part of the trip did 4800 joules.
In its basic form, you simply need to input the force and the distance from your scenario, and it will When you enter this mode, you will see 3 different sections that will allow you to calculate:This work calculator is smart. × .

How do I calculate work if only weight and displacement are given? At what angle is the force applied with respect to the ground? You might ask why we didn't just put the 2 newtons in the equation W=Fs. Work must be done against gravity to the top of the incline. ) A 64 N force is applied to the book at a 120° angle from horizontal and moves the book 3 meters in the horizontal direction. 1 6
Work in physics, however, has a very strict and clear definition. Work formula is made use of to compute work done, force or displacement in any problem.
The SI unit for work is the joule (J), and its dimensions are kg•m 2 /s 2. In physics, work = force x distance, so 5.6 N times 7.9 m = 44.24 joules. Enter measurements in US or metric units. Work is equal to the force into displacement, i.e. Let’s consider some simple examples to illustrate the concept of work.A 100 Newton force is applied to a 15kg box in the horizontal direction and moves it 5 meters horizontally. Work is done when an object moves in the same direction as the force is applied and also when force remains constant. 7 All you need to do is take the force, F, and multiply it by the distance the object moved. For the second part, we know that a 100N force moved the suitcase horizontally 8 meters, so the total amount of work done on the second portion of the trip is:Combining the two values from each portion of the trip yields:Work and energy in physics share a close relationship. Calculate square feet, meters, yards and acres for flooring, carpet, or tiling projects. Place a 20 N block at rest at the bottom of a frictionless incline.

A=4.0 m, b=3 m. How do I calculate work done if I know the time, speed, height, and weight?A 631 N force acts on an object causing a displacement of 40.3 m. If the force does 983 J of work, how can I calculate the angle between the force and the displacement?How far must an object move in order for a 38 N force to perform 500 J of work, if the angle between the force and the displacement is 0º?How do I calculate work if I know the weight and the speed rate?Include your email address to get a message when this question is answered.Work out as many problems as you can, this will ensure a thorough understanding.All tip submissions are carefully reviewed before being published
So plugging these values into our handy equation yields:Linda takes a 300 N suitcase up 3 flights of stairs for a total vertical distance of 16 meters. Calculate project cost based on price per square foot, square yard or square meter.
ISSN: 2639-1538 (online) 8 It works offline! This Calorie Calculator is based on several equations, and the results of the calculator are based on an estimated average. Then substitute the value into the work equation, and get the result. Calculator Use. You can find the horizontal component by doing 110 / 8.25 = 40/3 Newtons. When a ball rolls down a hill due to the force of gravity, when you pick up your backpack off the ground, when your car’s internal engine applies a force to make your wheels move; all of these events involve a force moving an object over a distance and so involve some work.
