CP Ch 4 Test Study Guide

Newton’s 3 Laws
Mass, Inertia, Weight, Friction, Net Force
F = W = ma = mg
ag = g = 9.8 m/s² = 10 m/s²
Mass – inertia – g relationship
Air Resistance
Sliding at constant velocity
Force addition and subtraction
Mechanical Equilibrium
Airplane thrust
Free Fall v and a

Units – m/s, m/s², ft/s, ft/s², N, lbs, slugs,

Equations – v = d/t, a = v/t, F = ma,
W = mg, a = F/m , m = F/a
