  • You gotta keep doing what youre doing sir.It helps alot!

  • @syronsuerte Thanks. We will. Glad to help.

  • i got a test with mr morin on friday, i didn't get any of this before. this video helped me out tremendously thank you very much!!

  • @DarkAwesomeness Please let him know it was one of my videos that helped. Mr Caruana

  • how would you write out the equation when the slope is at a constant decrease with it being only a scalar and not a vector? like in the video at 3:00 lets just petend there isnt a [E] under the meters. would it be slope= 4/4 or slope= -4/4 or slope= 4/-4, etc?

  • @vestraya In math you would solve for the slope and it would come out negative even if the axis was not labled[E] so the slope would be -4/4 = -1. In physics you would need to know if you were asked for the speed which is a scalar (1m/s) or asked for a velocity which is a vector (-1m/s =which should be written as 1m/s[West]). So you get the negative in the calculation but you may not need it to answer your question, it depends on what you are asked for.

  • in a distance time graph where the y axis is just total distance covered and not distance from the the startting position, will the graph shown for the last problem be a line that just keeps going up?

  • @PhysicsEH i get it, thanks you!

  • @henryz0r Glad we could help. Best of luck with your exam.

  • I have a Physics exam tomorrow and this really helped me understand!
