... Example : Two boxes and a pulley. Two boxes are connected by a cord running over a pulley. The coefficient of kinetic friction between box A and the table is 0.20. We ignore the mass of the cord and pulley and any friction in the pulley, which means we can assume that a force applied to one end of ...

1 WHAT IS PHYSICS?
... If you want to understand how an object (like a car, ball, person, or rocket) moves, you have to understand three things about what it means "to be moving." These three things "stick" to any object that moves, and are numbers that scientifically describe just how an object's motion is working. These ...
