Forgive my impertinent question. It seems reasonable to say that a 2.5kg ball is falling at a velocity of 12.5 meters per second, but if it is dropped from 8m, isn't it unlikely that it could fall faster than 9.81 m/s in one second? It has only fallen 8 meters and hasn't even fallen for a whole second yet. Can a graph be made to show speed and distance together?

+chris thomson Sorry I did not answer earlier I was out of town for a week. Do the math to calculate the time it would take to fall 8 m. You can see a listing of all my videos at my website, www.stepbystepscience.com

how do you know if the applied force equals gravity? also, how do you determine theta?
@stepbystepscience8 жыл бұрын
When you rise something at a constant velocity then the applied force is equal to the force of gravity. Theta is tha angle between the force and the direction of motion. You can see a listing of all my videos at my website, www.stepbystepscience.com

2:45 isn't the angle for the cos theta supposed to be the angle between direction of the two forces which are the applied force(Fa) and the force of gravity(Fg) ? so it should be cos180

How do you find out how much GPS something has just before it hits the ground?
@stepbystepscience8 жыл бұрын
GPS??? do you mean gravitational potential energy??? GPE = mgh, h for height. Right beofre it hits the ground the height is basically zero (0 m). Therefore the GPE is 0 Joules. You can see a listing of all my videos at www.stepbystepscience.com

+Brian Swarthout Sir why didn't you put height in the formula of work instead of putting ∆y?
@stepbystepscience8 жыл бұрын
+Faisalkhan Sasoli The height and the change in the y are the same thing. In this example 8m is the vertical height of the stairs it is not the "length" of the stairs. I can see now that this could be a little confusing from the diagram. You can a listing of all my videos from my website, www.stepbystepscience.com

Why?
@kasra20038 жыл бұрын
ISn't the final velocity of the ball after it's dropped is ZERO ??? because velocity ceases to exit after it hits the ground !! or final velocity should be named the velocity in progress . in this case the progress of initial let go of the ball and the momentum it gains before hitting the floor . Please someone could explain to me ?? THANK YOU IN ADVANCE !
@stepbystepscience8 жыл бұрын
+kasra2003 Sorry I did not answer earlier but I was out of town for a week. When something is falling we take the final velocity to be the velocity just before it hits the ground and stops. You can see a listing of all my videos at my website, www.stepbystepscience.com
