Question

Q.10 a) How does mass differ from weight?
b) Weight of a man on earth is 150N, and on certain planet is 25N. Take g
as 10m/s’on earth; find the mass of the man on earth and the planet. Also,
find the acceleration due to gravity on the planet.​

Answer 1

Answer:

$\mathfrak{ \huge{ \red{ AnSwEr}}}$

In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.

Answer 2

Answer:

mass of an object is referred as it is the measure of the object's internal property and Weight of an object is the measure of the force exerted on the object by gravity

m*g=150

m=150/10=15

150/6=25

means that planet is the moon

mass never changes from one planet to the other planet

15*g=25

g=25/15=1.66m/s^2
