Math Operation Crossword Puzzle Game
Math Cross Puzzle is math game that let you to learn basic math operations like as additioan, subtraction, multply and devide in crossword puzzle game style. The game play is you must put the numbers on the right places. and press submit button to see how many scores that you can get it. For every correct puzzle you will get 10 score, and the Total Score is show you are as Beginner, Competent, Pro, or Expert.
Spring Scale is a simple game that designed to simulate the technique of how to read of do measurement with the Spring Scale. This app is one of Computational Lab of Department Physics, UB productivity to increase the passion of student learning about physics in Elementary Physics Lab. You can try to measure how many mass at every object and interact with the scale.This is given the random mass for every section, and also you may find different object that to be measure.
The basic concept of this simulation, are based on spring forced that mathematically writed as W=-ky, where W is weight of object that to be measure (N), k is spring constant (N/m), and y is the deviation of spring (m). So if W=mg, with m is mass of the object (kg) and g is gravitational acceleration (m/s2).
The scale result of measurement shown that weight of object is about 1.325 Newton. With gravitational acceleration 9.8 m/s2, and based on equation W=mg, We can calculate the mass of object is about 0.1352 kg.
Neck Caliper game is an game that designed to simulate the technique of how to read of Caliper measurement results. This app is one of Computational Lab of Department Physics, UB productivity to increase the passion of learning about physics in Elementary Physics Lab.
Caliper mostly used at basic measurement on Physics Experiment. Most student need the concept to learn how to read Caliper scale, to get correct measurement result. Because if the student don't know how to read it, the experiment will be need extra time, just for learn how to read caliper scale. So with this game, student or user can learn virtually, and then check the result by him self and get ready to do real experiment on real laboratory.
Predicted Calc is a calculator that made by android base, and use genetic algorithm to get unknown value of variables that typed on the equation. Therefore, this app can also be use for finding root of polynomial equation, like an examples below: For example to find root of equation: x2-2*x-3=0 The steps is: Copy and write the equation without x and y, and with math sign operation, for example by using xo, so the equation can be writed as xo*xo-2*xo-3=0, because x and y was used by Predicted Calc as input variables. Press calculate botton to predict one of roots. Wait until Predicted Calc, approach the best value can be reach. Because using prediction method, Predicted Calc give error result, this error show how far the prediction give best value that can be reach by your device on that calculation, another calculation could be give the different result as same as or more better error value. Predicted Calc will give the result -1 and 3 with error=0, like screenshot below: For prediction ever…
