About this app

"Physical motion calculator" is a computer that performs various basic physical motion calculations. There is no function as an ordinary calculator. (Note: All current calculations ignore air resistance)
∙ It is a convenient calculator when you want to know the falling speed and falling time during free fall, and the speed after a specified time during the constant acceleration movement, and it is troublesome to calculate while putting the value into the formula. It may also be used when you have solved an assignment but want to check that the answer is correct.
The basic formula is posted in the app. In addition, if the formula is changed at the time of calculation, the formula is also included for reference (only for reference).


If you select the motion you want to calculate and enter a value, various calculation results will be displayed. For example, if you want to calculate from the initial speed and time at the time of vertical throwing, select “vertical throwing”. Next, select “1. Calculate from initial speed, time t” in that, and the value input screen will appear. Enter the initial speed and time and press the Calculate button. If you want to change the value of gravity acceleration, enter the same value as the initial speed. The output and the moving distance (displacement) when the specified time has elapsed are displayed in the output area at the bottom of the screen. It also displays the maximum speed from the initial speed and the time to reach it.
As described above, select the desired motion, enter a known value, and calculate the speed.
The calculation screen displays the target figure at the top so that you can see what kind of exercise you are doing.

Tap the red pen at the bottom right of the input panel to edit from the current value.

・ Ignore air resistance
・ The transformed formulas on the calculation screen are for reference only.
-When calculating using several formulas (oblique projection with elevation difference), there may be no formula on the calculation screen (because of various applications such as constant velocity motion and vertical throwing)
・ The unit is only a basic unit, so please change the unit if necessary.
・ If it is possible to calculate by fitting even under impossible conditions, we will calculate
・ The number of significant digits is 15 digits
・ We are testing, but if there is a bug, please send a bug
・ If it is popular, we will add functions that have many requests.
