Question

With the help of a graph,
derive the relation v^2-u^2=2as​

Answer 1

with with the help of a graph drive the relative V2– U2 =2as

U = velocity at time t1

V= velocity at time t2

a: uniform acceleration of the body along the the straight line

displacement covered during the time interval t2 -–t1 area ab t1 t2

S area of triangle ABA + area of a rectangle AA = t1 t1 area of trapezium.

S =1/2* Sum of parallel side x perpendicular distance .

S = 1/2 (v+u) t ....( Equation)

from the first equation for motion V= u+at ,

t=v–u/a

substituting in equation 1 we get

S=1/2 ( v+u) ( v– u)/a

or , V2 – U2 –2as

this answer is right

and please give me a thanks and star
