Comparison between electric charge and mass

Electric Charge:

1.) An electric charge can be positive, negative, or neutral.

2.) The electric charge of a body is always quantized and follows the equation: $q=ne$

3.) The electric charge of a body remains unaffected by its speed.

4.) Charge is strictly conserved.

5.) Electrostatic forces between two charged bodies can be either attractive or repulsive.

6.) Electrostatic forces between multiple charges can sometimes cancel each other out.

7.) A charged body always carries some mass.

Mass:

1.) The mass of a body is always positive.

2.) Unlike charge, mass quantization has not yet been established.

3.) The mass of a body increases with its speed.

4.) Mass is not conserved by itself as some of the mass may get changed into energy or vice versa.

5.) Gravitational forces between two masses are always attractive.

6.) Gravitational forces between multiple bodies never completely cancel out.

7.) A body with mass may not necessarily have a net charge.
