Motion Equations Mr. Kings Science Class

WORK WORK = FORCE X DISTANCE

WORK Feet or cm

WORK WORK = FORCE X DISTANCE Feet or cm Pounds or grams

WORK WORK = FORCE X DISTANCE Feet or centimeters Pounds or grams Foot pounds or gram centimeters

WORK WORK = FORCE X DISTANCE Feet or centimeters Pounds or grams Foot pounds or gram centimeters 10 cm

WORK WORK = FORCE X DISTANCE Feet or centimeters Pounds or grams Foot pounds or gram centimeters 10 cm X

WORK WORK = FORCE X DISTANCE Feet or centimeters Pounds or grams Foot pounds or gram centimeters 10 cm X 20 g

WORK WORK = FORCE X DISTANCE Feet or centimeters Pounds or grams Foot pounds or gram centimeters 10 cm X 20 g =

WORK WORK = FORCE X DISTANCE Feet or centimeters Pounds or grams Foot pounds or gram centimeters 10 cm X 20 g = 200 joules

WORK Lets try a word problem! Johneal pulled a 100 gram weight using a spring scale up the smooth side of a chalk board. The spring scale read 80 grams as she pulled it evenly 25 centimeters. How much work did Johneal do?
