Study Guides

Every section's key ideas, formulas and worked examples. The quizzes link here when he misses a question.

Newton's laws, normal force and tension, connected blocks, elevators, friction, and incline graphs. New numbers every time, in the same pick-from-a-list format as Quest.

Work, kinetic and potential energy, springs, conservation of energy, efficiency, plus ball-bounce graphs and skate-park energy bars from the class handouts.

Momentum and force, impulse, conservation of momentum, elastic and inelastic collisions, 2D collisions, and rocket propulsion.

Radians and angular velocity, centripetal acceleration and force, banked curves, fictitious forces and Coriolis, universal gravitation, and satellites and Kepler's laws.

Density, pressure and depth, Pascal's principle, gauge pressure, buoyancy, surface tension, flow rate, Bernoulli, viscosity and Reynolds number, drag, and diffusion.

Temperature scales, thermal expansion, the ideal gas law and kinetic theory, specific and latent heat, conduction, convection and radiation, the first law, heat engines, Carnot, heat pumps and entropy.

Springs and simple harmonic motion, pendulums, resonance, waves and interference, intensity, speed of sound, decibels, the Doppler effect, resonance in tubes, hearing and ultrasound.

Practice the Lab 3 worksheet: design the experiment, run trials, calculate KE directly and from PE, find the standard uncertainty and 95% confidence intervals, and decide if the two KEs differ.

Collide carts (elastic, sticky or bare bumpers), then check whether momentum and kinetic energy are conserved using Δp and ΔKE with 95% confidence intervals.

Balance a meter stick with torques, find the stick's mass, then build your own balance to weigh an unknown object and compare with the scale.

Measure a liquid's density, float a block, and use Archimedes' principle to find the block's mass. Is the scale reading inside your confidence interval?

Time a pendulum at small and large angles and test whether the period really is independent of amplitude.

Drop a hot (or cold) metal into water in foam cups, find its specific heat with a 95% confidence interval, and identify the mystery metal.

A skate park with live KE, PE and thermal energy bars, and a bouncing ball that draws its position, velocity and acceleration graphs. Predict first, then run it.
