Boolean algebra finds its most practical use in the simplification of logic circuits. If we translate a logic circuit’s function into symbolic (Boolean) form‚ and apply certain algebraic rules to the resulting equation to reduce the number of terms and/or arithmetic operations‚ the simplified equation may be translated back into circuit form for a logic circuit performing the same function with fewer components. If equivalent function may be achieved with fewer components‚ the result will be increased

Design Rationale It is known that the acceleration due to gravity (or g) is approximately 9.8m/s2 [down] or -9.8m/s2 [up]. What we are trying to do is design an experiment to measure and confirm this value. Our plan was to drop an object from a reasonable height and use a ticker tape timer to measure the amount of time and distance travelled between each time. The weight of the object used would have to be heavy enough that it would not be affected by air resistance. For example‚ you shouldn’t use
