All objects that oscillate have something called a natural frequency. At this frequency they will experience resonance and start oscillating with increasing magnitude towards infinity, or in the case …
Physics Mathematics Notation Euler Sine Cosine
When writing mathematical expressions, numbers and formulas that look quite different can mean the same thing. For instance, power series (an infinite series of terms added together) can be used to …

Pendulum Motion and Simple Harmonic Approximation
Technically the movement of a pendulum doesn’t quite match simple harmonic motion. However, if the angle theta is small enough, θ~sin(θ) In fact for angles less than 15 degrees the error will be …

Fear and Physics
If you have a tough physics problem, you might hesitate to even start it. That won't help your cause though..... Use lots of paper and just write down what comes to your mind. It might be …
Tension Free Body Diagram
If a vine is hung over a tree branch in the forest and two monkeys are hanging on both ends then the tension in the vine will be equal throughout the whole rope, since if it wasn't the vine would snap …
Simple Harmonic Motion SHO
Many things exhibit something that resembles simple harmonic motion (abbreviated SHO). Waves rise and fall with a regular pattern and a slinky oscillates. To analyze simple harmonic motion, we turn …
