L2 mechanics

Kinematic Equations (constant acceleration):

• Constant acceleration (with 3 graphs): Fendt

• Decelerating train (input initial velocity to get train to stop before light)

• Labeling v-t graph ideas (review of L1phy motion)

Vectors & Force Diagrams:

• Adding 2, 3, 4 or 5 forces, and finding Net F (HKNG)

• pulling mass up inclined plane with F-diagram (Fendt)

• inclined plane with F-diagram (GeoGebra)

• Mass accelerating on inclined plane (with F diagram): download & run java link (HKNG)

Torque:

• mass on bream with F-meter with possible non-90-degrees (download java and run) HKNG

• Balancing on beam Lab, Game (Phet)

Momentum:

• Momentum simulation (Phet - click HTML5 version) - keep it as 1-D collisions but change the elasticity from 100% to lower

• Impulse activity: Egg Drop: phy-classroom: shows values of F, v, p and impulse

• Conservation of momentum (Fendt) with elastic & inelastic

• Newton's Cradle (Fendt)

• Explosive conservation of momentum (Geogebra) with graph of v vs t instead of p vs t

• Conservation of momentum (Geogebra) with v vs t AND p vs t graphs for elastic & inelastic

Springs (and Energy):

• Hooke's Law Lab (Phet) look at all 3 parts!

• Masses on springs (Phet) check out effect of different planet's gravity

• Conservation of Energy Skatepark (Phet)

Projectiles:

• Projectiles with vectors (Phet)

• Another projectile animation with vectors (Geogebra)

• Tranquilize that monkey! (Geogebra)
