Lecture 10
... You push on an object and it moves. If you stop pushing an object, does it stop moving? Only if there is friction! In the absence of any net external force, an object will keep moving at a constant speed in a straight line, or remain at rest. This is Newton’s 1st Law, and it is also known as the Law ...

The Laws of Motion
... In terms of a reference frame, imagine you have an air hockey table inside a train moving 20 m/s relative to the ground. A hockey puck on the table, experiencing almost no friction, appears to not be moving but we know the train is moving so the puck must also be moving at 20 m/s relative to the gro ...

Hermann Minkowski (1864-1909), a German Professor of mathematics, born in Russia, developed a number system that seems appropriate for describing co-ordinates in a fourdimensional space-time continuum. In his approach, we may think of events in space-time that occur at a particular place and at a p ...
