Derive formula for kinetic energy
Answers
Explanation:
formula of kinetic energy is half MV square
Answer:
The formula for kinetic energy is Ek=1/2Mv^2
Explanation:
Derevation:
We studied three equations of the motion.
The realtion connecting the initial velocity(u) and final velocity(v) of an object moving with a uniform acceleration (a),and the dispalement (s) is
V^2-U^2=2AS........mark it as equation (1)
This gives
s=v^2-u^2/2a........mark it as equation (2)
We know that F=ma.Thus fromequation 1 and 2 we can write the work done by the force,F as
W=ma v^2-u^2/2a
OR
W=1/2mv^2-u^2......... mark it as equation (3)
If the object is starting from its stationary position then u=0,then
W=1/2mv^2......mark it as equation (4)
It is clear that the work done is equal to change in kinetic energy of an object.
If u=0,the work done will be 1/2mv^2
Thus the kinetic energy possessed by an object of mass, m and moving with a uniform velocity, v is
Ek=1/2mv^2
