@josephpallangyo8641 3 года назад

I always watch your videos "COGNITO",and I have found understanding instantly,thanks so much. So my question in this video of newtons laws 1 and 2 is that,why you have subtracted 42N and 30N?

@braedenreviewsbooks6692 3 года назад

They subtracted 30N from 42N because they wanted the resultant force. For example. There are 30N to the the left and 42N to the right so the resultant force is 12N to the right.

@redroses2082 Год назад

To get a resultant force u subtract smaller force from bigger force and the direction of resultant is always in the direction of bigger force

Physics (F=ma) test: “Without” applying the Energy from within you, choose an object of your choice, and apply only the Force or Net Force needed to push it away from you or pull it towards you. Please let me know if you’re able to. This is only a test. Thank you.

What about a golf ball in space? If an astronaut throw a golf ball( or a dice)in space, did it stops floating? Or it will cruise forever/ perpetually? If the dice stops, it means : the aether exist which causes the friction in space, or the About Michelson Morley experiment : Answer : the light is like the water is an exception for some experiments, thus that is unclear experiment. @Physics Videos by Eugene Khutoryansky you should prove it otherwise it mean : there is free energy in space ( it can be produced unlimited free energy in space, I think that is not possible, for example : if I have a generator in space and move only one time the axis of generator, it will spins around forever/ perpetually ( that is according your logic) , but I think not. Therefore need to prove it .

@wanna-ace-all-your-tests 7 месяцев назад

Hey! I was wondering if you could help with this one question thats been on my mind alot. 4:54 here you said that resultant force is found when you subtract one from the other but in your terminal velocity video you mentioned how the resultant force would be the sum of the resistive force ( air resistance ) and weight. Pls help me out!!!

@thesausageman5388 6 месяцев назад

In the terminal velocity video he meant that you would ‘add’ the resistive force to the weight to get the resultant force, but really you would take away. It wasn’t all that clear unless you paid a lot of attention though. If the force upwards is 50N and the force downwards is 80N, 80-50 = 30, so resultant force is 30N downwards

Resultant force. I What is it . What is the definition What is it a result of Is it the same as force Can you please explain, Confused from the beginning

@aijibs3833 Год назад

I dont fully understand how the particle could be changed in direction without a change in speed. For example, if i blew a pen that was originally heading my way to the opposite direction, the speed would be changed when heading in the opposite direction wouldn't it?

@redroses2082 Год назад

Imagine ur self in a car with constant speed u take a turn u feel ur self lean on the other side even tho u are not changing the speed the sudden change in direction causes change in speed (acceleration) also keep in mind velocity is vector had a direction so change in direction changes velocity even if magnitude is same

@IronMan-yt2rk 2 года назад

wait in newtons second law you say force is directly proportional to acceleration it causes but isnt it directly proportional to acceleration and mass?
