Newton's 2nd Law

Honors Physics Course Video 12
AP Physics B Cycle 3

This video introduces Newton's 2nd Law and discusses how to write 2nd law equations.

No questions, good video on Newton's second law. I remember doing the "lift" experiment freshmen year

[henryreed]

This makes sense, and I have no questions. I enjoyed the video and it was very informative.

Every opportunity I get!

Friction between your hands and the book, acting as two upward forces. The issue is that if you only have one hand there, then there's nothing to keep it pressed against your hand, so friction decreases enough for it to fall. The more you press an object onto a surface, the greater the frictional force.

We watched this video in class. No questions, but it may take me a little to get used to these equations.

[jwallwiz]

no questions here and the elevator experiment with the scale is actually one of the only things i vividly remember lab-wise from Freshman year

[chasewatson]

I understand this as well also and learned this last year so I understand it easily

[nikolasdiamondidis]

No questions. Very helpful. I don't know about the tower of terror so I think I'd still take my chances and go on it

[FlippedphysicsNet]

I actually used to have a drum kit once upon a time, though I was never that good. Piano and guitar are my instruments at the moment.

[ericlee]

You could also say that the net force is the same as the sum of the productions of this video

[priyalakhanpal]

I understood this video pretty well. Will we be given the equations?

[zacdav]

No questions. I had a lacrosse trip to disney and we rode the tower of terror 6 times in a row, great ride.

[chasewatson]

I understand this a lot better and I have no questions

[grahamdavis]

No questions. The way I think about elevators has changed dramatically

[jamiesoderlund]

no questions. I think you should keep up the drumming!

[madeleinefarnham]

No questions, I liked the tower of terror example though.

[brandonhresko]

Will you have these equations up on the board for tests like you did for the other equations? Thanks

[owenshoop]

I have no question other than the same one as Brandon.

[tylerkelley]

I think it will take some time for me to understand all the equations, also like everyone else said, will we be given these equations or not?

[briandestefano]

If its true that there are more then three dimensions, I'm not convinced of this, could I be pulled into one by an unbalanced force?

[rachelsindler]

Do we have to memorize the equations or will they be given to us?
