One lesson for each chapter of University Physics Volume 1, in the book’s order. The lesson teaches what that chapter says you need to know, then checks it.

  1. 1Units and MeasurementTwo commonly used systems of units are English units and SI units.
  2. 2VectorsA vector quantity is any quantity that has magnitude and direction, such as displacement or velocity.
  3. 3Motion Along a Straight LineDisplacement is the change in position of an object.
  4. 4Motion in Two and Three DimensionsThe displacement vector Δ r → gives the shortest distance between any two points on the trajectory of a particle in two or three dimensions
  5. 5Newton's Laws of MotionA free-body diagram is a drawing of all external forces acting on a body
  6. 6Applications of Newton's LawsThe normal force on an object is not always equal in magnitude to the weight of the object.
  7. 7Work and Kinetic EnergyThe work done against a force is the negative of the work done by the force
  8. 8Potential Energy and Conservation of EnergyFor a conservative force, the infinitesimal work is an exact differential.
  9. 9Linear Momentum and CollisionsThe law of conservation of momentum says that the momentum of a closed system is constant in time (conserved)
  10. 10Fixed-Axis RotationThe instantaneous angular velocity of a rotating body ω = lim Δ t → 0 Δ θ Δ t = d θ d t is the derivative with respect to time of the angular position θ , found by taking the limit Δ t → 0 in the average angular…
  11. 11Angular MomentumIn rolling motion without slipping, a static friction force is present between the rolling object and the surface.
  12. 12Static Equilibrium and ElasticityWhen a body in a selected inertial frame of reference neither rotates nor moves in translational motion, we say the body is in static equilibrium in this frame of reference
  13. 13GravitationThe weight of an object is the gravitational attraction between Earth and the object
  14. 14Fluid MechanicsAbsolute pressure is the sum of gauge pressure and atmospheric pressure
  15. 15OscillationsSimple harmonic motion (SHM) is oscillatory motion for a system where the restoring force is proportional to the displacement and acts in the direction opposite to the displacement
  16. 16WavesWave velocity and wavelength are related to the wave’s frequency and period by v = λ T = λ f
  17. 17SoundThe speed of sound depends on the medium and the state of the medium
