Question

1) What is mass?
2) how many different in quality and quantity ​

Answer 1

Answer:

1) Mass is a measure of the amount of matter in an object. Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it. An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity.

2) is that quantity is a fundamental, generic term used when referring to the measurement (count, amount) of a scalar, vector, number of items or to some other way of denominating the value of a collection or group of items while quality is (uncountable) level of excellence.

Answer 2

Answer:

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).
