If two objects have the same amount of inertia does it also have the same amount of momentum?

Answer 1

No they don't. The object with the larger mass of the two, or three or however much will have the greater or greatest momentum, because there is an inverse relationship between the momentum of an object and its mass.

Answer 2

Kinetic energy of a moving object, Ek = m * v2 /2, where m = the mass of the object and v = its velocity, while its momentum, p = m * v.

Ek is a scalar and p is a vector, because v is a vector. If all motions and forces happen along a straight line, then the scalar/vector distinction no longer matters -- velocity becomes speed and p can be represented by a scalar quantity.

Hence, for 1D problems, Ek = half of the product of p and v. Alternatively, we can express Ek as p2 / (2*m). The higher the momentum of the object, the higher its kinetic energy. Please see the related links about more detailed information on scalar, vector, and dot product. =====================================

Answer 3

MOM1 = M1 V1
KE1 = 1/2 M1 V12 = 1/2 MOM1 V1

MOM2 = M2 V2
KE2 = 1/2 M2 V22 = 1/2 MOM2 V2

If the kinetic energies are equal, then

1/2 MOM1 V1 = 1/2 MOM2 V2

MOM1 V1 = MOM2 V2

MOM1 / MOM2 = V2 / V1

If their kinetic energies are equal, then the ratio of their respective momenta is
the reciprocal of the ratio of their respective velocities.

So the momenta aren't equal unless the velocities are equal. But if the velocities are equal,
then in order for the kinetic energies to be equal, the masses must also be equal.

So bottom line, if two particles have equal kinetic energies, their momenta aren't equal unless their masses
are equal, i.e. their kinetic energies are equal because they're identical particles . . . their masses and speeds
are the same.

Answer 4

With "the same amount of inertia", do you mean "the same amount of mass"?

Momentum is the product of the mass, and the velocity. Therefore, in SI it has units of kg x meters / second.

Answer 6

Not necessarily. Inertia is the resistance of an object to changes in its motion, while momentum is the product of an object's mass and velocity. Two objects can have the same inertia but different momentum if they have different masses or velocities.

Answer 7

Only if they have the same mass and the velocity is directed in the same direction.

and volume should same and force should act on object should be displased.
