APPENDIX

Conversion Factors and Formulae to be used with Physical Sciences Final Examination

Conversion Factors:

1 meter (m) = 3.281 feet (ft) = 100 centimeters (cm) = 39.37 inches (in)

1 liter (l) = 1.057 quarts (qt) = 0.2642 gallons (gal)

1 kilogram (kg) = 2.205 pounds (lb)

The acceleration due to  standard gravity (g) = 980.6 cm/s2 = 9.806 m/s2

centi = 1/100            milli = 1/1000            micro = 1/1,000,000

1 mile (mi) = 5280 feet (ft) = 1.609 kilometers (km)

Formulae:

Force (F) = Mass (m) x acceleration (a)

Weight (Wt) = Mass (m) x gravity (g)

Work (W) = Force (F) x distance (d)

Power (P) = Work (W) time (t)

Kinetic Energy (K.E.) = mass (m) x velocity squared (v2)

Potential Energy(P.E.) = mass (m) x gravity (g) x height (h)

Frequency (f) = 1/Period (the time for one cycle of a wave)

Velocity (v) = acceleration (a) x time(t)

Average velocity = (vfinal - vinitial)/2
