Engineers re-create tsunami debris impacts to measure their force
In a tsunami, devastation is created by far more than the wave itself. Debris that hits homes and other structures plays a huge role in a tsunami's destructive power. But until now, engineers could only estimate the forces at work when...

Conservation of Momentum in Collisions
The video is a lecture on the conservation of momentum. It explains how momentum is calculated, how changes in momentum can be written in terms of force and time, and the concept of Newton's third law. The video then shows how these...
