Graphical Display of a Physics Simulation

2
Purpose and Scope

• Display objects graphically and information about
  those objects numerically on a GUI
• Allow user set-up of scenarios
• 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
• Spring Force
• Gravitation
• Electrostatics

4
Development Collision Detection

• Check if x coordinate between ends of ramp

• Check if y coordinate between bottom of ramp and
  desired center of projectile

5
Development Integration Method

• Modified Simpson's Rule
• Stores previous two acceleration values
• Finds equation for parabola through points
• Integrates from 0 to t

6
Results Kinematics
7
Results Spring Force
8
Results

• Projectile-projectile and projectile-ramp
  collisions are detected and a velocity change
  occurs as a response.
• Projectiles correctly apply gravitational and
  Coulomb forces.
• Ramps correctly apply frictional force.
