	Vector addition: this site has a feature for adding up vectors and other advanced vector operations
	Projectile motion: This is great for both lab and class
	Projectile motion: This is another very nice simulation from PhET. Excellent for both class and lab
	Conservation of Linear Momentum: you can experiment with linear momentum conservation here (elastic and inelastic collisions)
	Buoyant forces (Archimedes Principle): experiment with forces acting on a body  partially or completely submerged in a fluid. You can vary liquid density etc.
	Sine and Cosine Transformation: Another nice applet from Ron Blond, author of the micrometer caliper above. The applet shows how various parameters in the sine or cosine function changes the graph of the  function. This is useful for discussing SHM and related topics.
