I am not going to get into the mirror and lens equations, but rather, this simplified article is going to act as a cheat sheet for solving mirror and lens problems. When studying mirrors and lenses, you will frequently run into problems along the lines of “if I have a mirror and the focal p

The article linked above is about reflection! You experience reflections all the time. Mirrors are a great example. When you stand in front of a mirror, you will see a reflection of yourself in the mirror. How does this happen? When light rays hit a mirror, that

The article linked above is about the Doppler effect. You may have heard this name before. When is it used in life? Have you ever noticed how a siren from an ambulance, police car, or a fire t

The link to the article above talks about magnetic fields in general, but our simplified version here will simplify all of the right hand rules that you need to know to solve magnetism problems. Just as a disclaimer, it is highly advised that you have some b

The article linked above is all about tension force. Tension force is a bit hard to describe, but it is basically a force through a rope, string, or cable. Essentially, if you tie a rope to a box and you are pulling on the rope, then there would be a tension force. As an

The article linked above is all about beats! You might be wondering, what actually causes a beat? A beat occurs when two sound waves with different frequencies interfere with each other. That might sound a bit complicated, so I will break it down for you. Before we begin, I wan

The article linked above is all about angular momentum! Angular momentum is NOT the same as linear momentum, which is a topic that we have simplified on this website. Angular m

I personally feel like the word “torque” sounds quite scary. Essentially, torque is the same thing as a force, but in rotational form. Think about it like this: if you apply a force to something, you will make that object accelerate. If you apply torque to something, you

The linked article above talks about Newton’s Law of Universal Gravitation. The basic idea is this: there is a force that exists between any two objects with mass. To calculate this forc

The article linked above talks about centripetal force. Centripetal force is different from just a “force”, because centripetal force is any force that keeps an object moving in circular motion. The centripetal force for any object will ALWAYS point t

What exactly is power? Is it the strength of something? In terms of physics, power is the rate that work is being done. In other words, power is how fast energy is being transferred because work can be classified as the change in energy. The mathematical equation to calculate powe

The linked article talks about work. Work is a concept that is usually taught with energy, and this work is not the same thing as someone working a job. In terms of physics, work is exerting a force on an object and therefore causing that object to move a

Well, I’ve covered the first two laws from Newton’s Laws of Motion. The linked article talks about Newton’s Third Law so now I will be simplifying that down. Here is basically what Newton’s Thir

Coulomb’s Law includes an equation that allows you to calculate the force between two charged objects. An object can either be positively charged, negatively charged, or neutrally charged. When dealing with Coulomb’s Law, we are o
