šŸ’” A quick map of how the big ideas of this chapter connect together.

Force a push or a pull (unit: newton, N) Effects of force start, stop, speed, shape Types of force contact & non-contact Weight Earth's pull, in newton Muscular force contact Friction contact Magnetic / Electrostatic non-contact Gravitational non-contact, always pulls Floating & Sinking buoyant force vs gravity
Force — a push or a pull (unit: newton, N)
↓
Effects of a force
start, stop, change speed, direction or shape
Contact forces
need touch
Muscular force
action of muscles
Friction
opposes motion, more on rough
Non-contact forces
act from a distance
Magnetic
poles attract / repel
Electrostatic
charges attract / repel
Gravitational
Earth's pull, always attractive
Weight & Floating
weight = Earth's pull (N)
Weight vs mass
weight varies, mass constant
Buoyant force
liquid's upward push; float or sink
