CalcSE — Graphing Calculator
A TI-84+ style graphing calculator with complex-number support. Evaluate expressions, graph functions, view tables of values, and trace along curves.
Launch →2D Kinematics Simulator
Two balls roll off a table under Earth gravity. Adjust initial horizontal velocity and table height, then track horizontal velocity, vertical velocity, total speed, and elapsed time as they fall.
Launch →Projectile Launcher
Launch a single ball from an adjustable platform. Control initial velocity and angle, or set vx and vy directly. Graphs show horizontal velocity, vertical velocity, and total speed over time.
Launch →Projectile Target Practice
Launch a ball and try to hit a target. Click anywhere in the scene to place a ground bullseye or a 2 m-tall stick figure up to 100 m away. Simulation freezes on impact and reports hit or miss.
Launch →Block Pulled — Single Block
A single block dragged by an applied force. Adjust mass, force, friction, and initial velocity. Meant as a simpler starting point before students move on to the roped two-block system.
Launch →Roped Blocks Pulled — Moving
Two blocks connected by a force reader, pulled by an applied force. Adjust masses, friction, initial velocity, and the pull. The blocks travel across a striped background so motion is immediately visible.
Launch →Roped Blocks Pulled — Centered
Same physics as the moving version, but the blocks stay centered on screen while a desert scene scrolls past them — useful for comparing how different accelerations look against the same framing.
