- Physics Multiple assessment A Storyboard on Free Fall Done By: Tanisha Gupta 9C
- Heyy, That building seems to be soo tall...
- Yeahhh, I guess the approx height would be around some 490m..
- why don't we use it for our Physics assignment ??
- Yeahh sure that sounds great, so let's go to the terrace and through a ball and calculate it's final velocity...
- Aim: To observe free fall of an object and to calculate the final velocity of the object before it reaches the ground.Let's say we throw a ball from a building of height 490m. So here we know,S = 490U = 0m/sa = 9.8m/s2To calculate the time, S =ut + (at2)/2= 490 = (0t) + (9.8t2)/2= (9.82)/2 = 490= (9.8t2) = 490 x 2 = 980= t2 = 980/9.8 = 100= t = root 100= 10s
- Calculation of the final velocity
- Hence, t = 10sTo calculate final velocity (v),v = u + at= 0 + 9.8 x 10= 98m/sTherefor, final velocity is 98m/s.
- yay! we completed the work. I understood the concept very well now.
- yess! I too understood.
