Question

All formulas from class 9 NCERT book [PHYSICS]​

Answer 1

Answer:

Ch 8

average speed = total distance traveled/ time taken

average velocity = initial velocity (u) + final velocity (v) / 2

speed = distance / time

velocity = displacement/ time

acceleration = v - u / time

Ch 9

force = m( v - u) / t

force = ma

Ch 10

F = G ( M × m) / d square

g =G × M / d square

Wm = G ( Mm× m ) / r square
