$$W = 50 \cdot g \cdot 0 - 50 \cdot g \cdot 1.5 = - 75 \cdot g$$Īs you can see, the work is negative, since the weight force points downwards and the displacement points upwards. The general formula for work and for determining the amount of work that is done on an object is: W F × D × cos () where W is the amount of work, F is the vector of force, D is the magnitude of displacement, and is the angle between the vector of force and the vector of displacement. This online time clock uses a standard 12-hour work clock with am and pm or a 24-hour clock for military time. Since, when close to the ground, $U(h) = mgh$, you just have to calculate $U(A) - U(B) = mg \cdot h(A) - mg \cdot h(B)$. A beautiful, free online scientific calculator with advanced features for evaluating percentages, fractions, exponential functions, logarithms, trigonometry. Work Force Distance cos (theta) Where theta is the angle of force applied relative to the displacement of the object. Calculator Use Use this calculator to add up your work week time sheet and calculate work hours for payroll. INTRODUCTION The Work, power, and energy calculator are designed for education, for students learning physics, it enables the physics students to calculate work, power, and energy through various functions incorporated in this calculator. One of the Theorems relating work and energy is $$W_ = - \Delta U$$
