Elastic, inelastic, and completely inelastic collisions are treated. The required input varies depending on collision type, but may include masses, initial or final velocities, r (coefficient of restitution), KE (final kinetic energy), ΔKE (change in kinetic energy), or β (percent change in kinetic energy). Depending on input, results may include initial or final velocities or masses. Momentum and energy equations can be displayed as computed, if desired. Changes in the masses of the objects are permitted so that some two body nuclear reactions can be handled. Several examples are included. |

| **workenergyprinciple.zip** | 189k | 11-03-17 | | **The Work-Energy Principle** This program uses the Work-Energy principle to solve problems involving any number of forces (in a plane) applied to an object or a system of objects, pulleys, and springs. It treats objects as point particles, that is, it will not treat rotation (except pulleys). If a pulley has mass, it is treated as a separate object in the system. The program will handle some cases of motion on a curved path if friction is the only non-constant force which does work on the object. Either numerical or symbolic solutions can be found, although the symbolic solutions are sometimes slow. Equations are displayed as the program runs and are also copied to the home screen. Several worked examples are included. |

In time dependent cases, the values of the unknowns as well as expressions for them as functions of time are given. Several examples are included. |

| **planemo.zip** | 54k | 08-02-28 | | **Motion in a Plane with Constant Acceleration** This is a generalization of my program, Projctle(), to include acceleration due to forces other than gravity. For example, it can be used for a charged particle moving in a uniform electric field. The values of any 7 of the 11 quantities, {components of acceleration, initial position coordinates, initial speed and direction, final position coordinates, final speed and direction, and time} must be entered, then the program solves for the remaining 4 unknown quantities.

The program has been pretty well tested, but if you find a flaw, let me know about it. My email is swailsey2004@msn.com. I hope this program comes in handy, but a tip is to use it to check your answers rather than become dependant on it as a source of them. (and I take no responsibility for any problems that this may have, although with such simple syntax I don't see that happening, but just to be safe) |
