FORMULAS

Power = Work/Time Work = Force x Distance; In the same direction (Force in N) Force of Weight = mass x gravity (mass in kg; gravity on Earth 9.8 m/s²) REMEMBER: 2.2 pounds in 1 kilogram Potential Energy (P.E.): (Energy that is stored) mass x gravity x height (mass in kg; gravity on Earth 9.8 m/s²) Kinetic Energy (K.E.) : ½ mass x velocity²; KE= mv²

Units: Work: Joules Time: seconds Power: Watts or Joules/second; horsepower; How many watts are in a horsepower? 746 watts = 1 horsepower Force: Neutons Distance: m, km, cm, miles, feet, etc. Mass: must be in kg to use in formulas; convert pounds to kilograms P.E. kg x m/s² x m; kg x m/s² = N; N/m = Joules K.E. is Joules
