Graphical Display of a Physics Simulation

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
