Forces and Laws of Motion

(and some maths concepts)

Vectors and Algebra

• Scalars, addition and subtraction, dot-products, absolute value
• Speed and velocity
• Differential change: Velocity as the differential of change in position, acceleration as the differential of change in velocity.

Laws of Motion

• Motion and change, velocity and acceleration
• Updating discrete systems: calculating the next stage from the current state

Readings

• Freeth, Tony. “Decoding an Ancient Computer.” Scientific American 301, no. 6 (2009): 76–83. https://www.jstor.org/stable/26001660

Vectors

• Draw vectors and visualize vector algebra, same in 3d
• Magnetic field demo

Motion

• Pong

Forces

• Simple example of constant acceleration under gravity

Attractors

• Planets orbiting a sun. The motion is solely derived by Newton's law. The result illustrates Kepler's laws
• The movements of a planet as they appear in the sky to an observer on another planet
• ... and the same illustrated for the geocentric world
