What is Mass Vs. Weight in Physics? - [1-5-11]

In this lesson, we will discuss the difference between mass and weight and how these terms relate to physics. In physics, mass refers to the amount of atoms and types of atoms inside the object. Weight is the force of gravity on the object. So, on Earth, an object has mass and weight, but if the object is taken to deep space it will have no weight but still have mass. Mass relates to how much inertia a body has - how hard it is to accelerate an object. Mass has nothing to do with gravitational force.

I'm not going to lie you don't know me but you have been helping me pass college courses and I appreciate you more than anybody else on this planet do thank you sir

[richb]

I use these courses for my Grandson and does very good in class . A+

[pareshsokay]

Weight is a vector and mass is a scalar. Well done very nice explanation .

[rudranshparab]

I was looking for this and i found brief answers before. You dig dip into it. Thank You

[renukajaikaran]

Thanks Sir. This has really helped me clarify these concepts in great detail.🙂

[yuusufliibaan]

Nice lesson and really valuable, thank you dear teacher for the valuable knowledge you have given us.
Thank you again and again, God bless you as a teacher

20:00 try to think about that: near earth and in outer space,
m=wg that means that the interpretation of equivalent principle is incorrect.

how do you then become weightless in an aircraft simulating being in space. gravity is still present although weaker due to height? is weightless the wrong terminology?

[eslamelsofany]

Mr iason, is your statistics package cover all topics in statistics and i don't need any resource else to learn everything about statistics ?

[thepeach]

10/10 great. Now I know how those ufo’s are flying like that.

[MohammadAsif-yiqs]

W= mg
If body is at rest then there will no change in velocity and hence acceleration will be zero i.e g= 0 so
W= 0
If its wrong then why weight is zero in deep space?

Hi sir, for the Engineering Mechanics series could you make a tutorial on Truss Analysis? (Method of Joints & Method of Sections)

[jjsmallpiece]

At what height above the earth does the reduction in G start to become significant?

[frankroper]

Does anything affect the gravitational field other than size? You said the moon was 1/6th the size of the earth so the gravity was 1/6th that of earth but since the earth is spinning I was wondering if the speed an object is turning might also affect the gravity or does a rock like a large asteroid also have some gravity?

[ernestschoenmakers]

Well what i miss in this lesson that if you go into freefall tihen you're weightless..

[hemrajue]

I think weight is well understood by the Archimedes principal. Does
balance measures mass or weight?
I think mass because both the pans of balance are equally acted upon by gravity.

[niyonkuruidrissa]

10x again sir and l would like like to ask you to make alesson on all types of power . And much appreciation 💕💕💕

[s.w.]

Is there a playlist for this series? I cant seem to find it.

[lakshmig]

Sir since you said electromagnetism is your area of expertise i would be pleased if you explain the Maxwell equations and everything related to that in detail

[aminomar]

15:00 didn’t you notice that proves that the interpretation of equivalent principle is incorrect!
