Thermodynamics
Most of these are generated from Interactive PhysicsTM software
- One atom Gas
- Three atom gas
- Expanding gas
- Compressing gas
- Entropy Increase
- Time reversed entropy
- Heavy-light gas mixture
- Gas to Solid
- Gravitational Distribution
- Convection Cells
- Brownian Motion Observation
- Brownian Motion Explanation
Mechanics
- Conservation of Energy
- Pole vaulter Coonservation of energy
Chaotic Systems
- Double pendulum: non-chaotic
- Double pendulum: quasi-preiodic
- Double pendulum: chaotic
Relativity
Most of these are generated from Interactive PhysicsTM software. The first three show the same process (a bandit running along the top of a train) from 3 points of view (frames of reference)
- Bandit in train frame
- Bandit in Earth Frame
- Bandit in Bandit frame
These next two show a dropped ball in the train and earth frames
- Ball in train frame
- Ball in Earth Frame
These next two show a collision from an inertial frame and a non-inertial frame
- Inertial frame
- Non-inertial frame
Breakdown of simultaneity
- Simultaneous events in train frame
- But in the earth frame ....
These show Einstein's elevator equivalence principle. The first 3 are generated using Interactive Physics: a ball is projected through the window of an elevator.
- Stationary elevator, gravitational field
- Accelerating elevator, no gravitational field in Earth frame
- Accelerating elevator, no gravitational field in elevator frame
