Capacitors are an electrical component made up of two plates with an insulator between them.

Electrons flow onto one of these plates as current flows around the circuit. This gives one of...

In Physics, there are two types of numbers: scalars and vectors. Scalars are just a normal number, as we are used to. Vectors also have a direction associated with them. Thus, variables like temperatur...

There are three methods of energy transfer that we need to learn: conduction, convection, and radiation.

1. Conduction:

Heat is thermal energy, and in solid...

A freely falling object in air (or any other fluid for that matter) experiences two forces: the gravitational force and the force due to air resistance (or drag force).
While the gravitational fo...

From a Newtonian perspective, the equation for the speed of a satellite in circular orbit around the Earth at a radius r can be derived by equating centripetal acceleration to the acceleration due to g...
