Question

Derive Three equations of motion 1.)v=u+at 2.)S=ut+1/2at square 3.)2as=v2-u2 Class 9 physics

Answer 1

Answer:

(i) First Equation: Suppose a body has initial velocity ‘u’ (i.e., velocity at time t = 0 sec.) at point ‘A’ and this velocity changes to ‘v’ at point ‘B’ in ‘t’ secs. i.e., final velocity will be ‘v’.
