- Newton's Laws:
- Objects at rest remain at rest, in the absence of external forces; objects in motion remain in motion with constant velocity, in the absence of external forces.
- F = ma
- For every action, there is an equal and opposite reaction.

- Law of Universal Gravitation
- Energy:
- Kinetic energy
- Potential energy
- Each
**conservative force**has an associated potential energy

- Conserved quantities:
- Energy
- Linear Momentum
- Angular Momentum

- Stationary waves can be described by
- amplitude
- wavelength or wave number
- phase

- Travelling waves can be described by
- amplitude
- wavelength or wave number
- angular frequency or frequency
- phase
- wave speed

- Observers moving relative to each other see
events happen in slightly different ways;
their descriptions are connected by
the
**Galilean transformations**, e.g.x' = x - v*t

- Time flows uniformly everywhere.
- All objects have a position and velocity.
