Energy, Work & Power (20 of 31) Conservation of Mechanical Energy, Calculating the Final Velocity

[@dcs1187]

Thank you so much for making these videos!!! I would be failing without this!

[@stepbystepscience]

You are so welcome! Thank you very much for commenting.

perfect & clear explanation.

[@ugazbethebest8]

That was an awesome explanation, thank you for that. What would happen if the blocks were to be dropped from a lower height? It would have a lower pE, and a lower final velocity no? Or would the velocity be greater since you’re decreasing in PE and thus the KE increases?

[@MJ177brrr]

What do I do when there is resistive forces acting?

[@giovannibergado769]

i dont get it after you multiply both sides by 2 and then the formula changes when you square root

[@stepbystepscience]

Yes, you multiply both sides of the equation by 2 to "get rid" of the 1/2 and the take the square root of both side to get rid of the v2.

how the time wouldn't be the same?

[@stepbystepscience]

+jospin lionel Object 2 has a lower acceleration. You can see a listing of all my videos at my website, www.stepbystepscience.com

thank you so much you're so helpful A big thumbs up

[@ealhejaily]

great video but i am confused a bit:( how come acceleration is different? acceleration is g.

[@ealhejaily]

If I understood this correctly. Acceleration in m2 will be g.sinTheta. which makes t2 bigger than t1. Am I correct?

ealhejaily I get u ....i think 'g' will apply on m1 bcoz its free falling ... m2 is sliding down ...now even though we neglect friction but still a 'friction less' slide cnt be same as a free fall....so acceleration of m2 cnt be equal to "g". Its slight less
