It is the energy possessed by a body by virtue of its motion. For a body of mass m moving with velocity v,
K.E. is given by K = 1/2 mv2
Linear momentum p and kinetic energy k are related as
Note :
1. For two bodies having equal momenta; the lighter body has larger value of KE.
From K = p2/2m . If p is same; K α 1/m
2. For the two bodies having equal kinetic energy; the heavier body will have larger momentum. As p = √2mk
For constant k; p = pα√m . So larger the mass, more will be the momentum.
