Question

Derive the formula for the kinetic energy of an object of mass m moving object with velocity v

Answer 1

hi friends
they move with certain initial velocity 'u' and final velocity 'v' . 
lets now consider the initial velocity as 0
force = mass×acceleration formula is v²-u²= 2as 
or v2-u2/2a
w=f×s
or we get w=M×A×V2-U2/A2 { BECAUSE S = DISPLACEMENT}
When we take 'u' =0 then u get cancelled and strike out the a,s we get W=1/2 MV2

thankyou

Answer 2

Answer:

Explanation:

an object move with certain initial velocity 'u' and final velocity 'v' .  

lets now consider the initial velocity as 0

force = mass×acceleration formula is v²-u²= 2as  

or v2-u2/2a

w=f×s

or we get w=M×A×V2-U2/A2 { BECAUSE S = DISPLACEMENT}

When we take 'u' =0 then u get cancelled and strike out the a,s we get W=1/2 MV2
