Yes. Momentum is rigidly defined as the product of mass and velocity. Velocity describes both a speed and a direction. So let's take two metal balls. One weighs 10 kilograms (kg) and the other weighs 20kg. We roll the 10kg ball along a flat and level floor at 2 meters per second (m/s) and the 20 kg ball at 1 m/s. 10*2 = 20*1 so they have the same momentum. If you have a friend roll the balls for you to catch some distance away, making sure after a few tests to roll the lighter ball at twice the speed of the heavier ball, you will find that it "feels" as if both balls hit your hand with about the same force. Your hand is stopping each ball. That is a force which is defined as the rate of change in momentum. Stopping each ball will cause your muscles to exert about the same strength to stop each ball, even though one is moving at double the speed of the other. You will then feel that two objects can indeed travel at different speeds and yet have the same momentum.

If two objects have the same velocity do they have the same momentum?

No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)


Do Two objects of different masses freely fall with same momentum?

No.....because we need both mass and velocity to find the momentum if velocity is same that is 9.8m/s that is of free falling bodies.........mass will effect the final result.


If two different masses have the same kinetic energy their momenta is?

... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.


How can two objects have equal impulse?

Two objects can have equal impulse if they experience the same force for the same amount of time. Impulse is the change in momentum of an object, and it can be the same for two objects with different masses if the force and time are adjusted accordingly.


How can object with different masses have the same momentum?

Momentum is not just mass. Momentum is the product of mass x velocity.


What happens different mass fall from same height?

Objects with different masses will fall to the ground at the same rate in the absence of air resistance, due to gravity being a constant force regardless of mass. However, objects with different masses will experience different forces due to inertia, momentum, and friction when they reach the ground.


Is it true two objects with the same mass will always have the same momentum?

No, two objects with the same mass will not always have the same momentum. Momentum is a vector quantity that depends on both mass and velocity. If the objects are moving at different speeds, they will have different momenta even if they have the same mass.


How could two objects travailing at the same speed have different amounts of momentum?

Momentum is a vector and so obeys the laws of vector addition. These imply that the momentum of two two objects will be the sum of the individual momentum only if the objects are moving in the same direction.


Why do you need momentum?

Momentum is defined as the "Mass in Motion". It is a Vector quantity. It depends on two variables (Object Mass and Velocity) . Its direction is same as objects velocity direction. In physics momentum is required to specify the motion of the object . If two bodies of same masses having different velocities have different momentum , in a similar way bodies of different masses having same velocity have different momentum. So , in order to describe the motion of object clearly one of the tool in classical mechanics is momentum


Can two objects with the same volume have different masses if so why?

Yes, two objects with the same volume can have different masses if they are made of materials with different densities. Density is the mass of an object per unit volume, so objects of the same volume but different densities will have different masses.


How is it possible for objects to have the same volume but different masses?

Their masses are different. (Mass = density * volume)


How can it be possible for two objects with different velocities to have the same momentum?

Two objects with different velocities can have the same momentum if one object has a greater mass and a lower velocity while the other object has a lower mass and a greater velocity. Because momentum is the product of mass and velocity, if the product of mass and velocity for each object is the same, their momenta will be equal.
