Distinguish between electric charge and mass.

Answer:

 

Electric Charge	Mass
1. Electric charge can be positive, negative or zero.	Mass is always positive.
2. Electric charge is always quantised.	Quantisation of mass is yet not established.
3. Charge on a body does not change with its speed.	Mass of a body increases with its speed.
4. Electric charge is always conserved.	Mass is not conserved by itself as it can be changed into energy and vice versa.
