Hookes' Law, elastic materials, bouncing, coefficient of restitution, circular motion, centripetal acceleration and force, static and dynamic stability

Equations:

Hooke's Law: Force = - spring constant x stretching: F = -kx

Bouncing: Coefficient of Restitution = speed of separation / speed of approach

Centripetal acceleration a = v²/r toward center.

Air, fluids, pressure, density, number density, volume, absolute temperature, floating, Archimedes' principle, flowing fluids, Bernouli's principle

Equations:

Pressure = Force / Area

Pressure = density x g x height = ρ g h

Ideal Gas Law:
Pressure = Number density x Boltzmann's constant x absolute temperature = (N/V) k T
where there are N noninteracting gas particles in volume V, and k = 1.381 x 10^-23 Pa m³/K is Boltzmann's constant.

Archimedes' Principle: The boyant force on an object is equal to the weight of the fluid it displaces.

Bernouli's Equation: P + ρgh + ρv²/2 is constant in an incompressible fluid in steady state flow.

The SI unit of pressure is the Pascal. 1 Pa = 1 N/m². The atmospheric pressure is called 1 Atmosphere (1 Atm) and is about 10⁵ Pa.

The SI unit of Temperature is the degree Kelvin or degree Celsius. Water freezes at 0C and boils at 100C. T(Kelvin) = T(Celsius) + 273 K. Absolute zero is 0 K = -273 C.
