DISTANCE & DISPLACEMENT Page 3 in your comp book

Displacement vs. Distance DISTANCE the COMPLETE length of the PATH traveled by a moving object DISPLACEMENT the length of the STRAIGHT LINE PATH from a moving object’s ORIGIN to its FINAL POSITION

Scalar vs. Vector SCALAR A measured quantity that has NO DIRECTION Examples Distance, Time, Mass, Volume VECTOR A measured quantity that HAS DIRECTION SIGN SHOWS DIRECTION Example Displacement

One more thing… What is the Pythagorean Theorem? A 2 + B 2 = C 2

Examples Sign of displacement refers to the direction the object is moving. A bird flies. AA 5 ball cat meters rolls runsnorth, 58 meters then north. west. 7 meters south Distance = 512 8 m mm Displacement = -2 +5 m -8 m

Example A man drives his car 3 miles north, then 4 miles east. 4 mi East 3 mi North Distance 7 mi Displacement 5 mi Northeast What distance did he travel? What is his displacement from his point of origin?
