Simply because physicists discovered that it is a product that is conserved.
In collisions of two objects for example, if you add up the momentum before the collision the momentum will be the same after the collision.
Note that momentum is not something that has a concrete reality.
A rock sitting on the ground has zero momentum relative to us here on earth but has alot of momentum relative to someone on mars. It can not have zero momentum and alot of momentum at the same time, it depends on ones frame of reference. My point is that momentum is not at 'concrete" thing.

Is momentum and energy the same?
No. KE = 1/2mv2, and momentum = m•v, where m is mass in kg and v is velocity in m/s.
What is the speed of an object when it is moving so that its kinetic energy is 93.3 J and the magnitude of its momentum is 37.9 kg meters per sec?
To determine the speed of the object, you can use the formula for kinetic energy: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass, and v is the velocity. You have the kinetic energy and the momentum, but the mass is needed to calculate the speed. The mass can be calculated from the momentum by the formula p = m * v, where p is momentum, m is mass, and v is velocity. Once you find the mass, you can determine the speed using the kinetic energy formula.
When a 3.8 kg rifle fires a 13 gram bullet it experiences a recoil velocity of 2.4ms-1Calculate the velocity of the bullet?
Using the principle of conservation of momentum, we can set the initial momentum of the system to be equal to the final momentum of the system. The initial momentum is 0 (since the rifle and bullet are at rest initially), and the final momentum is the combined momentum of the rifle and bullet after firing. We can calculate the velocity of the bullet by dividing the momentum of the rifle by the mass of the bullet. Final momentum = Mass of rifle * Velocity of the rifle + Mass of bullet * Velocity of bullet 0 = 3.8 kg * 2.4 m/s + 0.013 kg * Velocity of bullet Velocity of bullet = - (3.8 * 2.4) / 0.013 ≈ -738.46 m/s, where the negative sign indicates opposite direction to the rifle.
What is the mass of an object multiplied by its velocity?
The product of an object's mass and velocity is known as momentum. Momentum is defined as mass times velocity and is a vector quantity, meaning it has both magnitude and direction. It is often denoted by the symbol "p."
What is Change in momentum times time?
The quantity change in momentum times time is equal to the impulse. Impulse is a measure of the impact or force involved in changing an object's momentum and is calculated by multiplying the force applied to an object by the time over which the force is exerted.
What would the formula be for mass and momentum?
The formula for mass is given as ( m = \frac{F}{a} ), where ( m ) is mass, ( F ) is force, and ( a ) is acceleration. The formula for momentum is ( p = m \times v ), where ( p ) is momentum, ( m ) is mass, and ( v ) is velocity.
What is momentum is equal to?
Momentum is equal to the product of an object's mass and its velocity. Mathematically, momentum (p) is defined as p = m*v, where m is the mass and v is the velocity of the object.
What is the formula for momentum is equal to mass times velocity?
The formula for momentum is given by the product of an object's mass and its velocity, expressed as p = m * v, where p represents momentum, m is mass, and v is velocity.
What is the formula to calculate momentum?
Momentum (p) is mass (m) times velocity (v), so p = mv
How are velocitymassand momentum related?
momentum is the product of mass and velocity. p for momentum m for mass and v for velocity. (p=m*v)
What is the relationship of the speed of an object and its momentum?
Momentum (p) is equal to mass (m) times velocity (v), so p = mv
How do you calculate momentum?
Momentum is calculated by multiplying an object's mass by its velocity. The formula for momentum is: momentum = mass x velocity. Momentum is a vector quantity, meaning it has both magnitude and direction.
How do you determine the momentum of a moving object?
Momentum is the product of mas and velocity . Its unit is kgm/s. P = m*v where P = momentum, m = mass v = velocity
Does a plane flying through the air have a momentum of zero?
No, it does not have a momentum of zero because the formula for momentum is p = m x v, therefore since the plane has a mass and it is moving, there is momentum.*p = momentum*m = mass (kg)*v = velocity (m/s)
Does a fish have momentum?
Yes, a fish has momentum as it swims through the water. Momentum is calculated by multiplying an object’s mass by its velocity, and as a fish moves through the water, it possesses both mass and velocity, resulting in momentum.
What formula of momentum?
The units are KgMs- why? Velocity is a vector Quantity and mass is a scalar quantity.
What equation can you use to calculate object momentum p?
The equation to calculate object momentum is: p = m * v where p is momentum, m is mass of the object, and v is the velocity of the object.
