One-dimensional collisions

* 1D collision of two balls: You can change masses, velocities, and elasticity (eta = h). The balls move only along a straight line. (It may look as if the balls go through each other, but obviously they don't.)

* Air Track - 1D collisions:
You can change masses, velocities of two carts on an air track (low friction). "e" sets the elasticity (0 = inelastic, 1.0 = elastic). "dt" sets how fast the animation runs. Click on the momentum bar on the right side to see values for velocity and momenta. http://www.explorescience.com/activities/Activity_page.cfm?ActivityID=20

Railroad cars - 1D collisions:
One car collides with another one and they couple together. You can change the mass of the stationary car. The moving car has a mass of 100, but you can change its momentum. How can you find the initial velocity of the moving car? It gives you the final momenta and velocities of the coupled cars.

Two-dimensional collisions

* Collision of two balls - 2D:
You can view it in lab frame of reference or in the center of mass frame of reference. You can change the relative masses and the angle it hits (see "impact parameter"). How can you determine the velocities before and after the collision?

* Spark Table - 2D collisions:
Two balls collide, leaving trails. You can change masses, velocities, spark frequency (how often makes marks). Leave the table angle at 0 degrees. Change to inelastic by clicking its box.

* Balls - 2D collisions:
You can change the frame of reference, the ratio of masses, the velocities, and the elasticity of the balls. (See the directions.) The original velocities (v1 and v2) show for the ball. Hold mouse down to see final velocities (v1 and v2), also given in components along line between their centers (vn) and the component perpendicular to that (vp).

Playing Pool - 2D:
it goes out in the opposite direction to how the ball will move bMove red ball and change its velocity to try to hit blue ball into a pocket. The velocity vector seems odd - it goes out in the opposite direction to how the ball will move - so think of it as the pool cue. You cannot take data from this one.
