Physics is everywhere around us. Every push, pull, lift, and movement involves the concept of work.
Drop a comment below: If you hold a heavy textbook at arm's length for 10 minutes without moving it, are you doing physical work on the book? Letβs see who gets it right! π
KEY POINTS TO REMEMBER
β
Work is done when force causes movement. β
Work = Force Γ Distance.
β
Unit of work is the Joule (J).
β
Positive work occurs when force and motion are in the same direction.
β
Negative work occurs when force opposes motion.
β
Zero work occurs when there is no movement or when force is perpendicular to motion.
