This document covers many topics in kinematics and dynamics including displacement vs distance, speed vs velocity, free fall, Newton's laws of motion, work, energy, and power. Key concepts discussed are motion graphs, forces, force diagrams, Newton's first law of equilibrium, Newton's second law relating force and acceleration, inclined planes, friction, impulse, conservation of momentum, Newton's third law, work done by forces, the work-energy theorem, conservation of energy, and uniform circular motion.
7. Work
-done by force in the same direction as displacement
- done by force in different direction
-done by a spring (graph)
Work energy theorem
W = ∆E W = ∆KE W = ∆U
