– D=RT distance = rate * time – Position is in meters – Velocity is change in position, in meters per second – Acceleration is change in velocity, in meters per seconds^2

Momentum = (mass)*(velocity)

– Fahrenheit and Celsius F = (9/5)C + 32 – Average human body temperature: 98.6 F

– Force of a spring = kx k is a constant and x is the amount of stretch or compression. – PE(spring) = 0.5kx^2

– Density = mass/volume – Increasing pressure always raises density. Increasing temperature usually lowers density. When water freezes, it is less dense than liquid water.

Molar mass is measured in grams per mole. You may need to calculate molar mass of a compound. This info is found in the periodic table. Example: NaCl has a molar mass of 58.35 (22.9+35.45) Na:22.9 Cl:35.45
