Momentum is not just mass. Momentum is the product of mass x velocity.
What else can I help you with?
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.
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
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.
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.)
Can objects with different masses have the same momentum?
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. JGS
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.
The momentum of an object is in the same direction as what?
The momentum of an object is in the same direction as its velocity. Momentum is a vector quantity that depends on both an object's mass and its velocity. When an object moves in a certain direction, its momentum points in the same direction as its velocity.
Will two cars of different engine capacities maintain the same momentum if driving at the same speed?
No, the momentum of the cars would not be the same. Momentum is proportional to both mass and velocity, so if two cars are moving at the same speed but have different engine capacities (implying different masses), then their momenta will also be different.
Is the momentum of the car travelling north different from the one of the same car when it travels south at the same speed?
Momentum is a vector. This means it has magnitude and direction. The magnitude will be the same. But the sign will be different. If north is positive, south will be negative. This is the only difference.
An objects momentum is the same direction as it's what?
An object's momentum is in the same direction as its velocity. Momentum is a vector quantity defined as the product of an object's mass and its velocity, so it carries the same direction as the object's motion.
Are impulse and momentum the same thing?
No, impulse and momentum are not the same thing. Momentum is the product of an object's mass and velocity, while impulse is the change in momentum of an object when a force is applied over a period of time. Impulse helps change an object's momentum.
