1. Graphical Display of a Physics Simulation
Steven Oetjen TJHSST Computer Systems Lab

2. Purpose and Scope Display objects placed by the user graphically
Display information about those objects numerically on a GUI
Allow use of multiple types of objects
particles
springs
ramps

3. Development Implement equations in several areas Kinematics
Dynamics/Newton's Laws
Conservation of Momentum
Gravitation
Energy and Work
Electrostatics

4. Development Other components must be added GUI Structure and Layout
Graphics Panel Distance and Time Scale
Support of Multiple Objects/Multiple Types and Classes of Objects
Support of Coordinate and Polar Vector Conversions
Collision Detection
Improved Integration Methods

5. Tests
Collision
momentum and kinetic energy must be conserved in both components
Contact with Ramps
projectiles must accelerate parallel to surface of ramp
projectiles colliding with ramp must have angle of incidence equal to angle of reflection

6. Results
For collisions between projectiles, x- and y-components of momentum and kinetic energy conserved
For projectiles in contact with ramp of any angle, projectile is accelerated in same direction as slop of ramp
For projectiles colliding with ramp of any angle, angle of incidence equals angle of reflection
