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? 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? The supposed Einstein quote from Skeptic reads “the world we have made as a result of the level of thinking we have done thus far creates problems that we cannot solve at the level of thinking at which […]

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 will be the pulse rate during heart attack? A very high or very low heart rate may reveal your risk for heart attack. For most people, a heart rate that’s consistently above 100 beats per minute or below 60 beats per minute for nonathletes should prompt a visit to a doctor for a heart […]

What happens if you put a pencil in a glass of water? As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). This light ray changes medium and subsequently undergoes refraction. As a result, the image of […]

Does your weight change in an elevator? When the elevator is moving, we will weigh our normal weight. Since we are already moving at the same speed as the elevator (up or down), nothing is affecting us to change our weight. However, when the elevator starts to go or stops, our body resists it. The […]
