Electricity and Magnetism

This is one of the most common concepts that will be tested on your physics exam. Whether it tells you to solve capacitance, resistance, current, or volts, you should know how to use the correct formula for each problem.

Kinematics Equations Problem

One of the most important and basic concepts in physics is Kinematics. You will need to understand all of its formula and which to use in different problem sets. Here is a random sample problem below.

Conservation of Kinetic and Potential Energy

Energy comes in many different forms. It can’t be created or destroyed, but it can move between objects and change forms. The energy of motion of a moving object is called kinetic energy, and is given by the equation KE = 0.5m(v^2) Where m is the object’s mass, and v is the object’s velocity. Another…

Converting between Metric Units

The Metric System is based on the fundamental units of measure for length, volume, and mass. Length: meter (m) Volume: liter (L) Mass : gram (g) Base units in the Metric System can be converted into units that are more appropriate for the quantity being measured by adding a prefix to the name of the…

Point Source Sound

The intensity of a sound is the amount of energy that passes through a given area in a given time. I= E/A*t This equation can also be expressed in terms of power because power is equal to energy over time. I=P/A Sound from a point source will radiate from the source in every direction (spherical)…

Limiting Reagents & Moles

In a Chemistry lab you are asked to figure out how many moles of Al2O3 can be produced from the reaction of 10.0g of Al and 19.0g of O3.

Setting Up a Basic Projectile Problem

In physics, the crux of any problem is finding what is unknown and then knowing it. In most basic projectile problems, these boil down to velocity, time, and displacement.

A short series of basic aqueous reactions

When two different aqueous solutions meet, it is important to know what happens. You could get a solid, a gas, or no reaction at all. This tutorial will provide a series of questions to test your knowledge, and assumes that you have at least a basic understanding of the fundamentals of aqueous chemistry.

Stoichiometry Helps Chemistry

EASY STOICHIOMETRY CHEMISTRY What is Stoichiometry? Stoichiometry involves calculations with understanding of basic concepts of chemical equations. It is a mathematical part of balanced chemical equations and reactant-product mole ratio. If mass of one of the reactants or products in a chemical reaction is given, mass of another reactant or product can be calculated using…

How To Calculate The Age Of The Universe

Have you ever wondered how astronomers calculate the age of the universe? In this tutorial, you will learn about the astronomical theories that allow astronomers to make such calculations, including the Big Bang theory and the expansion of the universe. You will also learn about several key astronomical observations that serve as evidence for these…
