F=maEarth 9.8m/s2Moon 1.6 m/s2
Weight: newtons, pounds

SI unit of force is the Newton (N)

N = ( kg m ) / s2

pressure = force / areaP = F / A

SI unit of pressure is the Pascal (Pa).

Pa = N / m2
However, kiloPascals (kPa) are more convenient to use.

Other units of pressure include: atmospheres, millimeters and inches of mercury, kilopascals, torr, pounds/in2

Gas Laws Boyle's Law; PV=k or P1V1=P2V2

inverse relationship
note: k = kg m2 s-2 = Nm = Joule energy
