... 1. Suppose the force of wind resistance (friction) is proportional to the speed of an object and in the direction opposite to the object's velocity. From a platform 10 m above the ground an object is thrown upward and it eventually falls into a hole in the ground 10 m deep. By drawing free-body diag ...

Summary of the unit on force, motion, and energy
... because moving in a straight line at constant speed is what things are supposed to do. Only when we want the velocity to change do we have to do something. The relevant and interesting part of motion is the acceleration, which is the rate of change of velocity: Acceleration = (final velocity – initi ...
