Newton's Second Law of Motion
States that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Newton's Law of Universal Gravitation
Calculates the attractive force of gravity between two masses separated by a center-to-center distance r.
Ohm's Law
Relates potential difference (Voltage), electrical current, and electrical resistance in an ideal conductor.
Kinetic Energy
The energy that an object possesses due to its motion.
Molarity (Molar Concentration)
Specifies the concentration of a chemical solute in a solution as moles of solute per liter of total solution volume.
Ideal Gas Law
The equation of state of a hypothetical ideal gas. It relates pressure, volume, gas quantity, and absolute temperature.
pH Calculation
Measures the acidity or basicity of an aqueous solution by calculating the negative logarithm of hydrogen ion concentration.
Dilution Equation
Relates concentration and volume before and after diluting a stock solution, maintaining conservation of solute moles.
