In case you didn’t know, the universe is a terribly hostile place for most lifeforms. At least, it is if you don’t have proper protection. Take our own star, for example. The Sun gives life to everything on Earth, but it is also a violent inferno that shoots off high energy particles that could seriously disrupt Earth’s natural systems. Fortunately, for us, our planet has protection. Ultimately, the Earth is encased in a magnetic field, which is generated by the rotating, liquid iron core at…

What is a scalar?  A scalar is a quantity that is fully described by a magnitude only. It is described by just a single number. Some examples of scalar quantities include speed, volume, mass, temperature, power, energy, and time.  What is a vector?  A vector is a quantity that has both a magnitude and a direction. Vector quantities are important in the study of motion. Some examples of vector quantities include force, velocity, acceleration, displacement, and momentum.
