1.	Can proofs of equations os motion be asked in exams in class 9?For example those V = U + AT proofs
Answer» Answer: PROVE V = u + at where u = initial velocity, v = final velocity, a = ACCELERATION and t = TIME period Explanation: We KNOW acceleration (a) = rate of change of velocity = timeinterval changeinvelocity = timeperiod finalvelocity−initialvelocity = t v−u ∴a= t v−u ora×t=v−u or at = v - u or at + u = v ∴ v = u + at

Answer»

Answer:

PROVE V = u + at

where u = initial velocity, v = final velocity, a = ACCELERATION and t = TIME period

Explanation:

We KNOW acceleration (a) = rate of change of velocity

timeinterval

changeinvelocity

timeperiod

finalvelocity−initialvelocity

v−u

∴a=

v−u

ora×t=v−u

or at = v - u or at + u = v

∴ v = u + at
