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

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
