###### Physics Spreadsheets

- Coulomb's Law and Electric Fields (XLS, 33K)
Enter up to 4 charges and their xyz positions, and the spreadsheet calculates the force on a fifth test charge at a specified field point P, the electric field at that same point P, and various other quantities.

- Polynomial (XLS, 38K)
Enter the coefficients of 2 polynomials and the spreadsheet multiplies them, and performs other operations.

- Quadratic Equation Solver (XLS, 34K)
Enter the coefficients of a quadratic polynomial, and the spreadsheet solves them and presents the answer in several different ways.

- Relativity (XLS, 36K)
Enter coordinates and velocities, and the spreadsheet does Lorentz coordinate transformations and velocity transformations in up to 2 reference frames. This spreadsheet also solves relativistic Doppler shift problems.

- Simultaneous Equations (XLS, 31K)
Solves simultaneous linear equations in 2 and 3 variables using Cramer's Rule.

- Thin Lenses and Mirrors (XLS, 31K)
Solves problems where some of the following quantities are given: object distance, image distance, focal length, lens position, image location.

- Vector Addition (XLS, 61K)
Enter the magnitudes and angles of up to 5 vectors, and the spreadsheet graphically adds them, tip to tail, and calculates the x and y components of each vector and of their sum. It also displays the answer in polar form. Select "re-draw arrowheads" to update the display. Excel's scatter plot does not have an "arrowhead" option when connecting points.
