Do I have to memorize kinematic equations for MCAT? Kinematic equations are the foundation to mastering MCAT physics. Yes you have to ‘memorize’ and know the standard formulas, but it goes deeper than that. You have to understand the units, when to use which equation, and be VERY comfortable applying these concepts to the more […]
How is temperature determined?
How is temperature determined? Temperature is the quantity measured by a thermometer. Temperature is related to the average kinetic energy of atoms and molecules in a system. Absolute zero is the temperature at which there is no molecular motion. There are three main temperature scales: Celsius, Fahrenheit, and Kelvin. Does reheating meat kill bacteria? Proper […]
Did Einstein say we Cannot solve our problems with the same thinking we used to create them?
How do you add two vectors using their components?
How do you add two vectors using their components? Again, the component method of addition can be summarized this way: Using trigonometry, find the x-component and the y-component for each vector. Add up both x-components, (one from each vector), to get the x-component of the total. Add up both y-components, (one from each vector), to […]

Is iron rusting in the presence of moist air a physical change?
Is iron rusting in the presence of moist air a physical change? Rust is a reddish-brown substance formed on iron when it has been exposed to fresh air and moisture for a long time. This process is a chemical change called rusting. What is the chemical reaction of rusting? Rusting is an oxidation reaction. The […]

What color of light has the highest frequency?
What color of light has the highest frequency? Violet waves What is the depression of light? Dispersion of light is caused by the change of speed of light ray (resulting in angle of deviation) of each wavelength by a different amount. Note: White light comprises of seven visible colours (VIBGYOR) whereas black (or dark) signifies […]
