What is the difference between rest mass and inertial mass? ( not from school or something so answer in your own words. Only answer if our know the topic and can explain. Copy pasting from the internet will be reported. You will get 12 points.)

Classical physics identifies only two types of masses known as inertial mass and gravitational mass. However, three types of masses are discussed in relativistic physics: rest mass, inertial mass, and gravitational mass. According to the principle of equivalence in Einstein theory of general relativity, the inertial mass and gravitational mass must be equal. The concept of rest mass is a new concept which isn’t discussed in classical physics. In modern physics, the concept of rest mass is very important, especially when we deal with low energy particles. The main difference between inertial mass and rest mass is that rest mass doesn’t change with the velocity of the particle with respect to the observer whereas inertial mass increases with the relative velocity of the particle with respect to the observer.
