Question

derive the formula of kinetic energy 1/2mv2​

Answer 1

Answer:

From the newton third law

v^2 =u^2+ 2as

v^2= 0 + 2as

v^2 = 2as .........................1

we know that.......

F = MA

A= F/M

now,

put the value of a in equation 1

v^2 = 2 ×F/M × s

1/2 mv^2 = F.s

Work done = Kinetic energy = Potential energy

1/2 mv^2 = Kinetic energy

Answer 2

bro you open your NCERT Book and open chater work an energy so you can found k.e energy brive because i don't no how uploaded photo on branily so sorry bro
