L3 mechanics
Mechanics Unit:
CoM & Impulse (1-D and 2-D):
CoM: 1-D and 2-D: PHET animation (use "advanced" tab for 2-D collisions)
2-D impulse vector diagrams (interactive vector subtraction)
2-D vector addition (total momentum) or subtraction (impulse): Geogebra
2-D vector addition, subtraction and net-zero: PHET in "equations" section
Circle, Satellites and such:
Conical Pendulum: One animation ... or this one (both from GeoGebra)
Conical Pendulum with forces HKNG (must download and run the java file)
Vertical Circle (roller-coaster) Surandraneth
Various Earth-Sun orbit simulation (Boston Uni)
Angular Motion, Momentum & Inertia:
what is a radian? (animated gif)
Torque, angular velocity, angular acceleration, rotational inertia and angular momentum: PHET turntable with bugs!
Rotational Kinetic Energy of tic-tacs: youtube from PhysicsGirl
different masses racing down ramp (mass distribution idea) GeoGebra
different masses rolling down ramp (showing calculation of Ekr and Ek) GeoGebra
angular acceleration from torque: GeoGebra
Person on rotating platform: GeoGebra
SHM (loads just for this):
Graphing circular motion displacement (animated gif)
Displacement Phasor, wave and motion of mass or pendulum (Geogebra) GOOD!!!
reference circle concept vert and hoirz (Surendranath: use dropdown menu: oscillations: SHM)
Interactive reference circles (with sine vs cosine wave)
mass on spring (HKNG) with ref-circle & y, v, a vs t graphs
Ref-circle with mass on spring AND graph of y vs t (Surendranath: use dropdown menu: oscillations: phase-graph)
How kinetic and potential energy change with location or time (Surendranath: use dropdown menu: oscillations: mass-spring oscillations: then either K,U vs x or K,U vs t)
