STEM Motion Box

STEM Motion Box is an iOS physics simulation illustrating projectile motion (i.e. kinematics). With the focus of precision, convenience and aesthetics.

Modes
Swap between modes such as Two Bodies or Projectile Playground.

• Two Bodies
In the Two Bodies mode, discover how two balls interact & collide with one another. Enjoy the freedom to set a different velocity for each ball, creating endless outcomes. This mode shows more statistics, including height-at-collision and distance-between-balls.

• Projectile Playground
In the Projectile Playground, experiment using a single ball. The simulation continues wherever the ball landed instead of restarting after each projection. Purple lines show the ball's current trajectory, whereas grey lines show the trajectory history of the ball.

Features (supported all modes) include slow-motion and pathing trajectories.

• Projectile statistics
Shows the essential statistics (such as peak-height, impact-time and displacement) of each projectile after all projectiles have landed.

• Slow motion
Slows the speed of the simulation, enabling the freedom to enjoy and observe the statistics.

• Trajectory pathing
During any ball's motion, there is a path created behind the ball to visually show itstrajectory.What
