J = the units of energy which one joule is (1 Newton)(1 meter) or (1N*m) = 1 J h = height above a reference level. Measured in meters (m) m = mass is always in kilograms (kg) Formulas used in this unit: Equation 6: Potential Energy = mgh 2 Equation 7: Kinetic Energy = ½mv You will need to apply your algebra skills to solve for

In general, when converting from base units (m, l, g, etc) or derived units (m2,m3, m/s, Hz, N, J, V, etc) to a multiple greater (kilo, mega, giga, or tera) than the base or derived unit- then divide by the factor. For example: 10m = 10/1000km = 1/100 km = .01km. When converting from base units or derived units to a multiple smaller (centi ...
n : index of refraction (no unit) n i: index of refraction incident side (no unit) n r: index of refraction refracted side (no unit) Ө i: angle of incidence (°) Ө r: angle of refraction (°) Ө c: critical angle (°) v material: velocity of light in a material (m/s) c : speed of light or any electromagnetic wave in a vacuum (3x108 m/s)
Basic Energy Units. Joule (J) = Newton meter. calorie (cal)= 4.18 J = energy required to raise the temperature of 1 gram of water by 1 C. Btu = 1055 Joules = 778 ft-lb = 252 calories = energy required to raise the temperature 1 lb of water by 1 F. ft-lb = 1.356 Joules = 0.33 calories.
d1 and d2 represent two different distances that object one or two are from the fulcrum or rotational point. d : distance between objects (m) m2 : mass two. π : pie (3.14 rounded) G : universal gravitation constant. Fg : Force of Gravity (N)
HT = Higher Tier only equations. kinetic energy = 0.5 × mass × (speed)2. k 2. elastic potential energy = 0.5 × spring constant × (extension)2. e k e2. 2. gravitational potential energy = mass × gravitational field strength × height. p = m g h. change in thermal energy = mass × specific heat capacity × temperature change.
