Derive the formula of kinetic energy with its definition.
Answers
kinetic energy - the energy due to motion of an object is called its kinetic energy
hi mate
kinetic energy = the energy possessed by a body by the virtue of its motion is called Kinetic energy an object in motion as the ability to do work and hence possesses kinetic energy
formula of kinetic energy
.................... ..........
letter body of mass M kg is moving with a velocity of V M / S. Retarding force of FM is applied on it to stop it covers as distance before coming to rest
force applied = FM
initial velocity = vm / s
final velocity = u m / s
as kinetic energy = work done to stop body
hence kinetic energy = FS
= m a×s. ( f= ma )..(i)
no, from third equation of motion
a= v²-u²/2s
=0-v²/2s.
=v²/2s
by putting the value of a in equation ( i)
m ×v²/2s×s
mv²/2
kinetic energy = m v²/ 2
