If your exam tests or graphical methods more heavily?

v2−u22=as⟹v2=u2+2asthe fraction with numerator v squared minus u squared and denominator 2 end-fraction equals a s ⟹ v squared equals u squared plus 2 a s 2. Projectile Motion

a=dvdt=dvds⋅dsdt=vdvdsa equals d v over d t end-fraction equals d v over d s end-fraction center dot d s over d t end-fraction equals v d v over d s end-fraction a⋅ds=v⋅dva center dot d s equals v center dot d v Integrating both sides within limits (

R=u2sin2θgcap R equals the fraction with numerator u squared sine 2 theta and denominator g end-fraction Unit 2: Laws of Motion

CBSE often awards step-by-step marks for derivations. Missing a step can cost you marks, even if the final answer is correct.

ω2=gl⟹ω=glomega squared equals g over l end-fraction ⟹ omega equals the square root of g over l end-fraction end-root The time period ( ) is therefore: If your exam tests or graphical methods more heavily

|Δv|v=|Δr|r⟹|Δv|=vr|Δr|the fraction with numerator the absolute value of delta bold v end-absolute-value and denominator v end-fraction equals the fraction with numerator the absolute value of delta bold r end-absolute-value and denominator r end-fraction ⟹ the absolute value of delta bold v end-absolute-value equals v over r end-fraction the absolute value of delta bold r end-absolute-value Dividing by time interval and taking the limit
