Step 2: Write down the work formula for change in velocity and place the values in it. W = 10,000 J Example: Work with velocity changeįind the total work done, if the initial velocity of an object is 10 m/s, final velocity is 50 m/s, and mass is 20 kg. Step 2: Use the work done formula and place the values. Example: Work with force and displacementįind the work done by a car if the force applied on the car is 20 N with a displacement of 500 m. S.I unit of work is Joule J or Newton-meter Nm.Ĭalculating work is absolutely simple, either you use work done calculator or above-mentioned formula for the calculation. The Work Calculator Physics is an online tool that uses the product of the two inputs, force and distance (in metric units), to find the value of the work done. In other words, it is generally represented as the product of force and displacement. The following Physics tutorials are provided within the Magnetism section of our Free Physics Tutorials.Each Magnetism tutorial includes detailed Magnetism formula and example of how to calculate and resolve specific Magnetism questions and problems. Work is the energy transferred to or from an object by applying the force along with displacement. Magnetism Physics Tutorials associated with the Work Done On A Magnetic Dipole Calculator. Here is the formula to calculate work from change in velocity. The work done formula can be expressed as:ĭ = Distance Work with change in velocity Work formula is generally used in physics to find the work done by an object. Work formulaĪre you looking for work physics formula? In this space, we will explain definition of total work, how to find work for physics problems, work equation for physics, and few examples to calculate work. It requires mass, initial velocity, and final velocity of the object to get the total work done. *I thank Stephen Selipsky for bringing Page's results to my attention and for his patient explanations.Total work done can be calculated with ease using this online work calculator for physics. As the universe expands and cools, however, eventually the black hole may begin to lose mass-energy through Hawking radiation. Indeed, any black hole with a mass greater than about 0.75% of the Earth's mass is colder than the cosmic background, and thus its mass increases for now. When work is done against frictional forces acting on an object, the. Work is also done when a force causes an object to move. So rather than shrinking, it would continue to grow. Work is done when energy is transferred from one store to another. SI unit for work is newton-meters (N.m) or. Therefore, whatever little energy it radiates, it actually receives more in the form of heat from the cosmos. Work calculator in physics to find the work done on an object which moves through a distance by a constant force. Enter your numbers below, the answer is calculated live. But that does not take into account the fact that such a black hole is colder than the cosmic microwave background radiation bathing it. Here are the step-by-step calculations to work out the Standard Deviation (see below for formulas). The lifetime of a $1~M_\odot$ black hole, therefore, is calculated as nearly 57 orders of magnitude longer than the present age of the universe. The latest version also correctly accounts for the black hole's effective area, light scattering, and the resulting change in its evaporation lifetime. The drop-down menus select the units of measure to be used for their corresponding input field.Īn added feature is the calculation of the "peak photon" wavelength, corresponding frequency, and photon energy, representing the peak of the blackbody radiation curve per unit logarithm (of wavelength or frequency) that corresponds to the black hole temperature. The Work of Frictional Force Calculator can be used to calculate the frictional force between a moving object and the ground and the work done by this frictional force against motion. I kept the unit, but decided to use instead the much more useful value of one solar mass as the initial mass.Īs in Wisniewski's version, specifying any quantity causes the others to be recalculated accordingly (see source). Wisniewski's original code included a fictitious unit of mass, the "standard industrial neuble", equivalent to a billion metric tons, from Will McCarthy's novel The Collapsium. The original idea belongs to Jim Wisniewski, whose page from 2006 ( link) appears to be no longer available available again, but since it is not archived by the Wayback Machine, I think my functional clone is still useful. This page contains a JavaScript calculator of Hawking radiation and other parameters of a Schwarzschild black hole.
