Difference between MASS and WEIGHT

Many times mass and weight are used to describe the same thing. However, these two measurements are different. In this video, I explain the difference between mass and weight.
Mass is a measure of how much matter something contains, which equals the number of atoms in it
Weight is a measure of how strongly gravity pulls on something

The SI unit for mass is kilograms
The SI unit for weight is the newton N

Thanks for stopping by MooMooMath and Science.

Your explanation is very nice. Thank you. I understood mass and weight more when I watched the video❤❤❤

[cheskaavneen]

Thank you very much you helped me in my exam on September 14, 2023 you deserved a new subscriber❤️🥰

Am i the only one that was sent her bc of school and just read the comments?

Did I hear that properly it's sounds like the heavier we are the more we love the earth or was it the opposite, anyhoo would weight be the amt of wh or ground we have to cover it, the amt of ey the amount of pressure we have to deal with and then the 3rd it how much we actually ate, one person can eat like a horsepower but not be one and it would depend on the weight of the food as well or the density of it or the mass of the food eaten, we need a lot more information about what these good and bad energy we are eating and unused energy is doing to our matter and to our mind, thankyou for your video

The best way to explain this add in water and buoyancy. Weight and masks are similar but at the same time opposites. An object can have the same amount of mass and the same amount of weight. No matter if you change its size. If you make an object smaller. No matter how light and object seems. It can sink because it's weight is greater than its size. It is the balance of size and weight. Where does mass come into this. An object mass is the amount of matter that is that it is made of. It can be made of the same amount of matter. That means an object can be heavier while being smaller. It carries a great amount of mass in a smaller space. Oh you can say a great amount of weight in a smaller space. Still what makes it different. The mass of the object can change but the weight does not. An object can be lighter in the water than what it is on land. Yeah it can also seem heavier in the water. But that is only truly affected depending on the size. That's what mass comes in. Usually when a object weighs more it gets bigger. But when mass supplied the object can maintain the same weight while being smaller. Even can become smaller the more it weighs.

So basically mass depends on the usual weight(excluding multiplying with g) of an object on earth and weight varies on different planets.

What if we standardized mass on Mars?

THIS HELP ME PASS MY SCIENCE TEST. THANK YOU

[amyjbell]

Thank you so much for this content! It was a wonderful tool to help my smart, curious little boy understand mass!

An additional factor, besides location, that effects weight is acceleration of the reference frame. Under the principle of equivalence, an accelerating reference frame and a stationary object in a gravitational field are equivalent. So if I get on an elevator with a spring scale, the objects weight will change when the elevator accelerates. However a balance with a fulcrum would continue to show the same mass.

Also, "the amount of stuff" is a bit vague. One can get into a circular argument about how much mass said "stuff" has. A better definition is the net amount of force, needed to cause an acceleration, divided by the rate of acceleration.

Nice job! I find it amazing how many even "University Physics" professors (University Physics = Calculus-Based-Physics) fail to ensure their students get this. The simplest example is if I use a comparative balance with a 1Kg reference object, and I put an unknown substance as the counter object that levels the balance, the mass of that unknown object is also 1Kg. Now if I go to the moon and put the 1Kg reference object and the same unknown object as the counter - guess what? They are still equal because their masses are still equal. However their weights (gravitational force) will be a different value as from Earth (but still, they are equal in weight to each other too). Life is good indeed with enlightenment ...

[cactiboi]

So Mass and gravitational force= Weight on an object

[iberomagazine]

Gravity is an effect of bending the psacetime, not a force I underestand Einstein said
how do we eat that

[shudufhadzomulaudzi]

it good but i do not understand what you are talking about

[sweetstonegypsy]

that one detail inserted at 2:48 (amount of matter = number of atoms) is the part I never heard. is it the number of atoms or their combined atomic numbers?

[Layarion]

...is mass how many atoms an object is made of?

[danet]

Sound like “all right, all right, all riiight”. 😅

[madsea]

Im still confused asf. I have a mass of lets say 80kgs.(i weight 80 kgs) so is my mass actually 80kgs divided by9.81? Or since i am on the ground and have no acceleration shouldnt i deal 0 Newtons of weight on earth since 80kg × 0 acceleration is 0. I know that if i jump for 1 second i accelerate down 9.81 meters. And in that moment i pressure the earth with 9.81×80=784 Newtons of force. Is acceleration constant 9.81 when we are not falling?

[thebooca]

"verse" vs. "versus". One is correct, and the other is in this video.
