In Excel, the sin and cos function take arguments in radians, where 360 degrees = 2p radians. Excel writes p as PI(). So the formulas we want are: v_x_init = v*cos(theta*PI()/180), v_y_init = v*sin(theta*PI()/180). In A3 write: Projectile fired at speed v at angle theta degrees to horizontal. In A5 write v=, in A6 write theta=.
15 sie 2022 · Projectile Motion with Air Resistance Using 4th Order Runge-Kutta. UPDATED: 08/15/2022. DOWNLOAD EXCEL FILE. This Excel workbook computes the trajectory of a spherical projectile with fluid drag included. It also demonstrates some additional things that one can do with the Excel/VBA combination.
This is the next in a series of projectile motion tutorials for creating 2D trajectory models using numerical analysis of projectile dynamics (including aerodynamic drag). The trajectory formulas were derived in the previous tutorial.
The mathematical formula when converted to Excel formula becomes: =B7*TAN(RADIANS(angle))-((9.8*B7^2)/(2*velocity^2*COS(RADIANS((angle)))^2)) Where the cell B7 contains the value of X, and downwards.
To model a 2D projectile motion with air drag we used so far four columns of formulas: vx, vy, x and y. Let’s express velocities function of past coordinates and use them within the current coordinate formulas so that we can eliminate the two velocity calculation columns from the worksheet.
plot the total projectile speed along the trajectory - We can find the total speed from the X and Y speed components using Pythagoras theorem - The data for the total speed will be placed in the range J26:J2100 - To the right there is a snapshoot of the finalized calculation area of the spreadsheet - We will add a new scatter chart (green)
Set up an Excel spreadsheet to perform trajectory calculations for you. Your spreadsheet should look like the one farther down the page. The yellow cells are the input cells.
