IBPH Ep. 3 Speed, Velocity and Acceleration - Part 3 of 3

[chrschrls1]

Please keep making videos they are helpful and in some cases more helpful than my physics 110 class lectures

hy THANKS FOR THIS VIDEO, VERY GOOD, MY BOOK COSTED ME AROUND 160 DOLLARES, COULD YOU MAKE MORE EXAMPLES, TO WORK WITH, SOME EXAMPLES GIVE YOU TILL 3 TIMES INTERVALS AND SOME DISTANCES, A COMPLICATED EXERCISES DIFFICULTY TO SOLVE. THANKS.

thank you ...your vid helped me a great deal :)

i gave you 5 stars :)

i think you switched the values of the accelerations at 4:00

if its going to the right it should be positive 1.4, if its moving to the left it would be -1.4

Hi there. The direction of the acc. may or may not coincide with the direction of motion. In fact, the direction of the acc. coincides with that of the resultant force. What I was trying to show with this example is that, regardless of what you call positive direction, if your interpretation of the numbers is correct, you get the correct direction for acc. I did, indeed, change the direction to show that whichever method you use you get the acc. to the LEFT (in both cases!) and a value of 1.4.

Nice! Can you make some more videos?

Hi there. Thanks for your comments. I'm hoping to add one or two episodes over the Easter break.
