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.
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. =====================================
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.
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.

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.
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
Inertia is related to mass; you might say that inertia IS mass. The objects which have the most inertia are the most massive objects. Those are also the heaviest objects, since mass affects weight.
It has a non-zero momentum. It also has non-zero kinetic energy.
True, Because say if you have one acorn in a basket, The basket will be easy to move. Now lets say if you have enough acorns to fill the basket to the rim, The basket will be harder to move because of its weight and inertia.
Inertia is matter's unwillingness to slow down, speed up, or change direction in any way. It is also related to the matter's momentum. Momentum is caused by the body's velocity as well as the body's direction. If the velocity of the matter is increasing, or the body changes its direction, it can be said that the body of mass is experiencing inertia. When the body is accelerating (changing in velocity), the momentum of the matter is also changing (F=ma), thus mass and acceleration is related by momentum through inertia.

no,it also cant have inertia
skateboard.....if velocity is zero,then momentum is also zero.
To find the magnitude of momentum you use the formula: p=mv So, if an object has a mass (and if it exists then it would), and if it is moving (has a velocity), then yes, it has momentum.
It has a non-zero momentum. It also has non-zero kinetic energy.

Inertia and Momentum in FootballInertia is a mass's resistance to changes in its momentum. Objects that have greater mass have greater inertia, so they are more difficult to move when they are at rest and more difficult to stop when they are moving. A 320-pound NFL nose-tackle has lots of inertia. A runt like me who weighs a buck fifty and change, not so much. The nose-tackle is gonna be hard to move out of the way, so blocking him will be difficult. And if a running back carrying the ball runs into him, the play might end right then and there. If he ran into me, well, let's say that he would easily overcome my inertia, knock me into next week, and take it to the house.Which brings us to momentum. Momentum is also related to mass, but it is also related to velocity. If an object is at rest, it has zero momentum. A moving object, however, has momentum. Double the speed and you double the mo. Triple the speed, triple the mo. If a running back runs fast, he will build up momentum. He can use that momentum to overcome another player's inertia. If he runs into the nose-tackle, he'll need lotsa mo to overcome his inertia. If he runs into me, he won't need much.Just to complicate this a bit, an object with momentum has kinetic energy, and energy can be used to do work. To do work you must apply a force, and it's that force that can change another object's momentum. Since mass can't change, it stands to reason that velocity must change. So when the running back picks up a head of steam and plows into me, he's gonna change my momentum in a big way. I'm gonna go flying like a little kid's rag doll.
Just moment of inertia is incomplete requirement as the axis about which it is to be measured is also very important
Inertia is the tendency of an object to resist a change in motion. An object would have inertia while moving and also while at rest.
