## Wave Interference

Waves have the unique property that they can simultaneously exist in the same place. When two waves occupy the same space, their functions are added together. When waves have opposite signed values when they pass through each other, they cancel out. This is known as destructive interference. When waves have same signed values when they…

## Motion of objects under gravity

Have you wondered why an apple hits the ground when it falls from a tree but why the moon does not hit the earth? In this tutorial, we will look at different types of motion under gravity.

## Principle of Air Conditioning

In this tutorial, we will look at how we can transfer heat from a low temperature region to a high temperature region.

## finding average speed

In situations where you are given different speeds and the average speed is required, you need to keep in mind that the average speed is by definition: total distance/time elapsed. People get this wrong all the time, trying to do s= (s1+s2+s3+.. )/(number of s’s). Be careful.

## Classic Mechanics Problem – Newton’s three laws of motion

Newton’s three laws of motion is the most frequent topic that you’ll definitely be tested in high school or college mechanics physics courses. The first law is the law of inertia, which means objects will stay in the current motion (static or dynamic) unless an unbalanced force F applied. Second law is the formula F…

## 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…

## 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)…

## 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.
