Chapter 10: Dynamics of Rotational Motion
... Torque has units of N·m. Despite the fact that this unit is the same as a Joule it is customary to leave torque expressed in N·m (or foot·pounds). Engineers will often use the term "moment" to describe what physicists call a "torque". We will adopt a convention that defines torques that tend to caus ...

... What force does the floor exert on the block? (b) If a rope is tied to the block and run vertically over a pulley, and the other end is attached to a free-hanging 10.0-lb weight, what is the force exerted by the floor on the 15.0-lb block? (c) If we replace the 10.0-lb weight in part (b) with a 20.0 ...

Chapter 1 INTRODUCTION AND BASIC CONCEPTS
... Newton’s laws: Relations between motions of bodies and the forces acting on them. Newton’s first law: A body at rest remains at rest, and a body in motion remains in motion at the same velocity in a straight path when the net force acting on it is zero. Therefore, a body tends to preserve its state ...

... When the fly hit the truck, it exerted a force on the truck (only for a fraction of a second). So, in this time period, the truck accelerated (backwards) up to some speed. After the fly was squashed, it no longer exerted a force, and the truck simply continued moving at constant speed. Follow-up: Wh ...
