I have pasted in the list of features from the introduction on the Frink page ()- I never knew there were so many weird ones! (What do you measure in sturgeons? in crocodiles? Read and find out.) Some of them have amusing comments -he's scathing about the candela.įor those with a short attention span like me, here are some of the features of Frink. Use parentheses to keep units and numbers together in a denominator, or parts of fractions together in exponents. One tip: while it has a very predictable order of operations, it isn't always what you meant. Many other features that are often useful but not explicitly physics-oriented are also built-in, such as working with currency conversions, historical inflation-adjusted values of the dollar and the the GB pound, natural language translations, number theory functions, arithmetic in bases up to 36. It can act as an interactive desk calculator with a terminal-window like interface and command and results history, or as a serious programming tool with GUI, graphics, self-evaluation, anonymous functions, regexp, some OOP, Java introspection etc., etc. It has been under development for several years and still gets multiple updates nearly every week, so it has reached a good state of refinement. It installs with just a couple of clicks on regular computers of any OS as well as smartphones, or it can be used via a web interface. Arbitrarily-dimensional, non-rectangular, heterogeneous arrays (but not matrix math, only a little symbolic algebra, no calculus to speak of.) It has advanced interval arithmetic to keep track of error bounds, if desired. It uses arbitrary-precision math or rational numbers when possible. User-defined units may be added, too.) Very good time and calandar functions, with astronomical functions and units, leap seconds (or not, if you prefer). If the object gains or loses height relative to a gravitational body, then its change in gravitational potential energy should also be considered by adding the gravitational energy component to the equation.It only seems to have been mentioned a couple of times in passing, but Alan Eliasen's Frink calculator and programming language ( ) makes unit conversions simple (converting to SI internally then back to any desired target units. Where W is the work done on the object and ΔKE is the change in kinetic energy of the object. The equation for the work-energy principle is given as: This relationship, known as the work-energy principle, is very useful when solving problems in classical mechanics. These are the same units as energy because work is equal to energy. customary unit of work is the foot-pound. The SI unit of work is the joule, and the U.S. Where W is work, F is the force applied to the object, θ is the angle between the directions of force application and object displacement, and d is the displacement. If the force applied is NOT in the same direction as the direction that the object is displaced, then the equation for work is given as: When force that is applied to an object IS in the same direction that it is displaced like shown above, we use the general work equation.
