2. Mechanics

Relative Velocity:

• Crossing the river: Geogebra

• another river crossing: Suranrandeth: kinematics: boat & river

Graphs of motion:

• Const Acc graphs: Geogebra

• More const acc graphs: Fendt

Projectiles:

• Projectiles with vectors (Phet)

• Another projectile animation with vectors (Geogebra)

• Tranquilize that monkey! (Geogebra)

Forces:

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

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

• Forces (diagrams and both frictions): PHET

• Forces on a box with both frictions: Geogebra

• Inclined plane (force diagram and both frictions): Geogebra

• another Inclined plane (force diagram & friction): (HKNG) download and run java file

• and another Inclined plane (force diagrams & friction): PHET: download and run java file

Momentum:

• Momentum simulation (Phet) - 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
