INTRODUCTION TO ELECTRONICS: Metric Prefix Conversions ( Part 2 )

The number 1 can be formed via the establishment of a ratio of logically related quantities: A = A ( A / A ) = 1 A = B ( A / B ) = 1 And, ( B / A ) = 1 Furthermore, the product of any number multiplied by 1 is theContinue reading “INTRODUCTION TO ELECTRONICS: Metric Prefix Conversions ( Part 2 )”

INTRODUCTION TO ELECTRONICS: Electrical Units and Metric Prefixes

Physical realities would be meaningless without internationally standardized definitions that quantify their existence. Within the field of electronics, there are electrical units of measure that are so common that becoming familiar with them is highly advisable for new students. It is important to note that the aforementioned electrical phenomena occur in measured quantities that areContinue reading “INTRODUCTION TO ELECTRONICS: Electrical Units and Metric Prefixes”

ENERGY AND MOMENTUM: The Joule

The International System of Units ( SI ) uses seven base units to describe seven fundamental quantities that can be measured by scientists: Symbol Name Base quantity second ( s ) time meter ( m ) length kilogram ( kg ) mass ampere ( A ) electric current kelvin (Continue reading “ENERGY AND MOMENTUM: The Joule”

AP PHYSICS: Average Speed

Q: A distance runner has just finished her race. During the first 3 kilometers, she ran with a constant speed of 5 meters per second. During the latter 7 kilometers, she ran with a constant speed of 14.4 kilometers per hour. What is her average speed for the race? A: First, take note that theContinue reading “AP PHYSICS: Average Speed”

AP PHYSICS: Conversion Fractions

If we multiply the number 1 by a unit A, we end up with one unit of A: 1 x A = A We are at liberty to substitute A with any quantity we wish: 1 x 5kg = 5kg 1 x 6s = 6s 1 x 100m = 100m Furthermore, 1 x A =Continue reading “AP PHYSICS: Conversion Fractions”

KINEMATICS: The ” architecture of motion. “

Q: A mass m is moving horizontally across the surface of the earth with a velocity of ( v ) = 30 m/s . The mass approaches a ledge with an edge situated 100 m above the ocean. The mass eventually moves off the ledge and falls until it reaches the ocean’s surface. Calculate theContinue reading “KINEMATICS: The ” architecture of motion. “”
