Gravitation (2 of 17) Calculate Your Weight Two Different Ways
Вставка
- Опубліковано 8 вер 2024
- This video shows you two different ways to calculate your weight of Earth; (1) using Newton's Second Law of Motion and (2) using Newton's Law of Universal Gravitation.
Newton's second law states that the force is equal to the mass times the acceleration. Newton's law of universal gravitation is know as an inverse square law. The force of attraction between two objects with mass is directly proportional to the mass of the objects and inversely proportional to the square of the distance between the two objects.

Thanks! This has been very helpful.
Thank you..it is helpful
What's your weight difference at noon versus midnight? (Factor in the sun's pull & changing distance from the sun)
OK??
@@stepbystepscience Sun's force of gravity at your noon minus same at your midnight about 0.00074 kg, ( 0.03 ounces) ?
Yes, probably not very much.
Thank you!
You're welcome!
Thanx its really very helpful for me
If you can reply asap that’d be great. How do you find distance with the mass of 1 object and the force of attraction ?
thx
I really hope you have videos for Coulomb's law and electric fields. Maybe even magnetic fields. I am sure if you explain it I will actually understand them lol
I have videos for all of those topics, just search Step by Step Science Coulombs Law, for example.
And great that you find the videos so helpful, thanks for the comment.
hi sir, do you have any videos about Newton's three law pf motion?
You can see a listing of all my videos at my website, www.stepbystepscience.com, then go to Physics and then Newton's 2nd Law.
thank you so much sir, you help a lot of students a lot specially who is just doing self study just like me , more blessings for you sir
How are you converting to Newtons when kilograms and m/s are different units?
You need to convert this different units to kg•m/s before transform it at newtons
escuse me sire what if the its in grams not kg
Then you must convert to kg first, before putting the values into the equation.
@@stepbystepscience thank you sir your video really helped
You are very very wrong the weight and gravitation formula cannot be equal
Why ..... weight is the force applied to an object.........it can be earth ..... ......so suppose 100n then it applies force on you by 100 n ........ so when we do universal law of gravitation , we are finding the force between the two objects ................... and that is weight
