Question

What is the difference between Charge and Mass?
(2 points max)​

Answer 1

Answer:

Charge is of two types, mass is only of one kind. There are two types of forces (attraction and repulsion) between charges, but there is only one kind (attraction) between masses. ... Charge has SI unit coulomb, the SI unit of mass is kg.

Answer 2

1. Mass is the measure of inertia of a body while, charge is the measure of the electrical properties of the body.
2. Force acting between two masses can be gravitational or nuclear (force binding the protons and neutrons in nucleus), while forces between two charges can be electrostatic or gravitational.
3. Forces between two masses is always attractive while forces between two charges maybe attractive or repulsive.
4. Mass can never be zero (although the rest mass of a photon and some other sub atomic particles is zero), while charge can be zero (neutrons).
5. Mass of a body depends on the speed of the body at speeds comparable to the speed of light, while charge doesn't depend on velocity.
