We're at the Porsche test track to learn all about acceleration. Unit 2 Segment C: Acceleration and Kinematic Equations We're back at the Porsche test track to learn all about acceleration. Kinematic ...

This is a classic introductory physics problem. Basically, you have a cart on a frictionless track (call this m 1) with a string that runs over a pulley to another mass hanging below (call this m 2).

Suppose you have a cylinder on an ramp and you let it start rolling down. What will be its acceleration? Great question, right? I like this because it brings in many different concepts in introductory ...

It's impossible to talk about football these days without talking about the problem of big hits. The giant dramatic collisions between players moving at high speed are at once one of the great ...
