[oiramormedeiros]

Man, you've taught me so much over all the years!

[sciencestuff]

still watching these vids. love your style bro!

[XsnowyOo]

i kinda love how you start all ur vids saying "what is going on guys?!" :P it awesome :3

[michellelam]

thank you very much:) helped me a lot in my upcoming physic tests!

[DulksVenee]

Momentum is when an object has mass and velocity. Inertia comes around when you try to change the momentum

[Karim-udkl]

My life become a nightmare when i first become to studying  physics!!

Actually Newton 2 states that sum of forces cause acceleration,
so: Sum of Forces = mass * acceleration.

[Philmomon]

Momentum in and of itself is of no interest. Trying to give it a definition other than mass times velocity is like trying to define energy. It is only of interest in context of collisions or other contact interactions. When Newton's second and third laws are applied, equal and opposite forces result in the law of conservation of momentum which can be used to predict outcomes.

[jasoncummings]

not true centripital motion states otherwise also just because an object appears to be at rest doesn't mean it is true. Force is relative so if you and a baseball are sitting still in a field that field is still moving through space as the earth travels around the sun etc....

Think about that!

[sameerroshan]

so whats the difference between momentum and Inertia? Dont they both sound the same? like ya the more mass it is the harder it will be to start it to move or stop it from moving? so do we say that its happening due to momentum or due to inertia?
Or does momentum only comes into place when an object is in motion?(which brings the velocity component?" If the object is at rest do we say that it has 0 momentum(but inertia is never 0)?

[monofono]

lol the advertisement at the begining of the video was about buckyballs

[ivikkivi]

What the heck happened with the end of the previous video?

[Revyrun]

where's the acceleration 0
if it's in space then it's ok because of the absence of gravity but on earth there's a force that doesn't let you sink deeper in. If the gravity is pushing you with 9.8 N then the earth is pushing you with 9.8 N
There's acceleration but you're just caught in the earth's web

[rpgmc]

F = Mass * acceleration
so if acceleration is 0 ; then Force is 0 ? :0
Think about that !

[CheyenneAnastacia]

now I have problems with Inertia again

[TheLawrence]

Earth is Pushing at the same force that gravity pushes you then it will result 0 :D

[TheLuigi]

The earth doesn't move or spin. Steven Hawking can prove so....

[drvinodkumarv]

Sir, y r u inculcating negative feelings on viewers by talking negative about puysics ?!
