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 writ…

This is the french version of YP Projectiles, a projectile motion simulator. YP Projectiles simule le mouvement parabolique d'un projectile. Plusieurs vecteurs et graphiques peuvent etre affiches pendant la simulation. Nouveau dans cette version: un graphique de l'energie mecanique, de l'energie potentielle gravitati…

New MacOS software to learn kinematics YP Rectilinear Motion 1.0 is targeted toward physics teachers and physics students. It allows the user to plot a graph of velocity as a function of time with simple mouse clicks. The program uses this graph to build a graph of position vs time, and a graph of acceleration vs time…

YP Reflection is designed to assist teachers and students when they study the laws of reflection in geometrical optics. The program provides the user with a laser source that can be moved and rotated, and with a large quantity of mirrors that can be moved and rotated. The normal to the mirror, the angle of incidence, t…

Learn how a shadow is formed! YP Shadow simulates a light source projecting the shadow of an opaque body on a screen. Using the mouse, it is easy to change the position and size of the light source, position and size of the opaque body, and position of the screen. YP Shadow draws the rays of light used to mark the boun…

YP Simple Pendulum 1.0: Kinematics and dynamics of a simple pendulum. YP Simple Pendulum simulates a simple pendulum, allowing to study its motion, the forces exerted on it, and its various forms of energy. It is easy to change the suspended mass, the length of the string and the maximum angle between the string and t…

YP Slider Crank simulates the motion of a piston activated by a slider crank mechanism. The crank is in uniform rotational motion (constant angular velocity), causing the piston to move with a variable acceleration. Relative lengths of the crank arm and the connecting rod may be changed easily. During the simulation, i…
