Yp Projectiles

Price (Shareware): $20 US YP Projectiles is a projectile motion simulator used in physics classes. To simulate a trajectory, the user chooses the initial velocity (magnitude and direction), the vertical displacement component and the gravitational acceleration. The software then draws the parabolic trajectory and writes its main characteristics: range, maximum height reached, etc. During the simulation, it is possible to display three vectors: acceleration, velocity and position, and four graphs: acceleration, velocity, position and energy versus time. Many trajectories can be superposed in the same window. Trajectories, numerical data and graphs may be printed or copied to be used in other software. Trajectories may be also saved as PICT files. New in this version: YP Projectiles 1.1 features a new graph displaying mechanical energy, kinetic energy and gravitational potential energy versus time.
