In general terms, E = mc^2 regards energy liberated when various types of subatomic collisions occur ( and typically dislodge a nucleus ), with m = mass ( kg ), and c = speed of light ( 3.0 * 10^8 m/s ). E/m = constant, and although different, a system in which gases undergo elasticContinue reading “GAS LAWS: The Ideal Gas Law.”

CHEMISTRY: What Quantity Does a Mole Describe?
CHEMISTRY 101: WHAT IS A ” MOLE “? HOW DOES THE QUANTITY DESCRIBED AS BEING A ” MOLAR ” QUANTITY CONNECT THE INVISIBLE SUBATOMIC WORLD TO THE VISIBLE WORLD? A balanced chemical equation is representative of a chemical reaction ( RXN ). For example, water is known to be made of two hydrogen ions +Continue reading “CHEMISTRY: What Quantity Does a Mole Describe?”
MATHEMATICS: Is The Earth Really Round?
Disclaimer: The earth, according to current mathematical models and observations, is not flat. ROUND-EARTH MATHEMATICS : In determining the rotational speed of the earth, we must first assume that the sun is positioned an exceptionally far distance from the earth. If this were not the case, snow, water, and complex biological life would be non-existent.Continue reading “MATHEMATICS: Is The Earth Really Round?”
ENERGY AND MOMENTUM: Artificial Gravity in a Spinning Spacecraft.
Q: A team of engineers is building a spaceship to go to Jupiter. Their design includes a gravity ring, a spinning section where (in the ring’s reference frame) astronauts are pushed outwards by the centrifugal force. In their current design, the ring has to spin once every ten seconds in order to provide the sameContinue reading “ENERGY AND MOMENTUM: Artificial Gravity in a Spinning Spacecraft.”
HEAT AND THERMAL ENERGY: Fahrenheit, Celsius, and Kelvin Scales
What relationship exists ( if any ) between heat and temperature? The concepts of heat and temperature are akin to the relationship between the number of moles of a substance and the molarity ( M = moles / L ) of an associated solution. Recall that a mole is a quantity of substance ( atomsContinue reading “HEAT AND THERMAL ENERGY: Fahrenheit, Celsius, and Kelvin Scales”
ENERGY AND MOMENTUM: ( x ) and ( y ) Vector Components of Motion.
Q: A steel ball of mass 10 kg moves due East at 5.0 m/s. It collides with a rubber ball of mass 5.0 kg moving at 10 m/s due North. After the collision the steel ball moves at an angle of 60° East of North with a speed of 4.0 m/s. What is the velocityContinue reading “ENERGY AND MOMENTUM: ( x ) and ( y ) Vector Components of Motion.”
HEAT AND THERMAL ENERGY: Thermal Expansion of Solids and Liquids.
The subatomic structure of solids and liquids have a profound influence upon how they react to a transfer of thermal energy. Solids have a relatively fixed or rigid structure, whereas the molecular structure of liquids allows for greater expansion and compression. Measurements have shown that ( in general ) a linear relationship exists between theContinue reading “HEAT AND THERMAL ENERGY: Thermal Expansion of Solids and Liquids.”
