This video takes you to a speedway in New York. It explains the weight of the car and the impact the car creates during a wreck. The video shows you the wall around the track, made of foam, that increases the impact time during a wreck. The narrator also mentions mass, velocity, impulse, and change in momentum. Run time 04:20.

A simple conservation of momentum problem involving an ice skater and a ball. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. (06:00)

This NASA video segment explores how Newton's Laws of Motion apply to the lift of an airplane. An instructor at NASA's National Test Pilot School teaches that for an airplane to overcome the downward force of its weight, it must change the momentum of the air molecules colliding with the wings. This is accomplished by changing the air's vertical velocity through increased propeller speed, sharpened angles of attack, widened wings or curved wings. Onscreen formulas and calculations represent the forces mathematically. For example, in one part, the instructor derives a formula from Newton's second law to calculate the minimum flying speed of an aircraft. The instructor then flies the aircraft to test his calculations. Run time 14:15.

Angular momentum is constant when there is no net torque. This video, which is suitable for high school students, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time (10:12)

A rather dizzy Professor Bowley sacrifices his well-being in the name of science. Explains and shows momentum. Some of this video is for higher level students, but there are some experiments that are done that could be interesting to younger students. Video is of good quality and would be good for high school students. Run time 07:07.

An old momentum with a new twist. Kepler's second law of planetary motion, which is rooted here in a much deeper principle, imagined a line from the sun to a planet that sweeps out equal areas in equal times. Angular momentum is a twist on momentum -- the cross product of the radius vector and momentum. A force with twist is torque. When no torque acts on a system, the angular momentum of the system is conserved.

(When you click on the link, please go to Video #44 for this particular video.) The new meaning of space and time make it necessary to formulate a new mechanics. Starting from the conservation of momentum, it turns out among other things that E = MC 2. (29:02)

If The Mechanical Universe is a perpetual clock, what keeps it ticking away till the end of time? Taking a cue from Descartes, momentum -- the product of mass and velocity -- is always conserved. Newton's laws embody the concept of conservation and momentum. This law provides a powerful principle for analyzing collisions, even at the local pool hall.

In this interactive activity adapted from Wake Forest University, learn about the principle of conservation of momentum. Two carts colliding on an air track demonstrate how momentum is conserved in a closed system. Observe six different scenarios—a moving cart colliding with a stationary cart of lesser, equal, or greater mass in both elastic and inelastic collisions—to see how the motion of the carts changes after each collision.

Stephen Gioia visits a race track to take a look at momentum and impulse. He talks to drivers and checks out the safety features built into the wall of the track, and the cars. This video will help you understand how the duration (time) of a collision can reduce the impulse of a crash (04:20).

A 28.8 g yellow air hockey disc elastically strikes a 26.9 g stationary red air hockey disc. If the velocity of the yellow disc before the collision is 33.6 cm/s in the x direction and after the collision it is 10.7 cm/s at an angle 63.4° S of E, what is the velocity of the red disc after the collision?
