The solution for this problem is a straight-forward application of our two rigid body kinematics equations relating the motion of point A back to point O: ...

Specialization is for insects.” So, in the interest of not being insects, here are my top-five physics equations you should know. 1. Newton’s Second Law I’m sure you've seen this one before ...

Intended for first responders, the original Provoke was a morphing karambit with a “kinematic” system that deployed the blade by drawing it up and out while allowing the user to maintain their grip.
