Question

Two object A and B of mass M and 2M with velocity V and V/2 respectively. which one will have greater inertia and greater momentum. give reasons

Answer 1

object B will have more inertia. as inertia is directly propotional to mass. both of them will have same momentum as p=M x V, where p is momentum.

Answer 2

Momentum = velocity x speed

momentum A = M x V = MV
 momentum for B = 2M x V/2 = MV

Therefore both objects will have the same momentum of MV kgm/s

2) Inertia is dependent on mass. The more the mass of an object, the more the inertia. Therefore object B with more mass will have more inertia than object A with a lesser mass.
