## 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.
