Question

Q. 1)Differentiate between mass and weight. (atleast 4 point).
Q.2)Define the following term :-
a) thrust
b) pressure
C) relative density

Answer 1

mass: 1 . mass cannot be zero while weigh can be zero.
2. mass is the quantity of matter present in it. while weight is a type of force that is attracted by the gravitational force.
3. SI unit of mass is kg while SI unit of weight is Netwon.
4.mass doesn't depends on gravity. but weight depend on gravity

pressure: thrust/ area
