Momentum

Why does a skater spin faster as she draws in her arms? Why does a gun lurch backwards as its bullet shoot forwards? Why would you prefer to be hit by a speeding ping-pong ball than a barely moving truck?

The answer to all these questions is momentum. Find out about linear momentum, angular momentum, and the conservation of momentum here.

Circus Physics: Conservation of Angular Momentum

Why do acrobats tuck their arms and legs close to their bodies? It makes them spin faster, by conserving their angular momentum, that is, their momentum of rotation. Don't miss this video! More...

Angular Momentum

Rotating things will go on rotating forever unless something interferes with them. They have "angular momentum," which is a bit different from the momentum of things moving in straight liens. More...

Momentum

The momentum of an object is its mass times its velocity. So a stationary object has no momentum. And a tennis ball moving fast enough could have more momentum than a truck.
