What is momentum in physics?

Momentum in physics is a measure of the quantity of motion of an object. It is calculated as the product of an object's mass and its velocity. Mathematically, momentum (p) is defined as:

p = m * v

Where:
p = momentum
m = mass of the object
v = velocity of the object

Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of momentum is the same as the direction of the object's velocity. In a closed system, the total momentum before a collision or interaction is equal to the total momentum after the collision or interaction, according to the principle of conservation of momentum.

Momentum is a vector quantity that describes the motion of an object. It is defined as the product of the mass of the object and its velocity. The SI unit of momentum is the kilogram meter per second (kg m/s).

Momentum is a conserved quantity, which means that the total momentum of a closed system remains constant over time. This means that if two objects collide, the total momentum of the system before the collision is equal to the total momentum of the system after the collision.

Momentum is an important concept in physics because it can be used to predict the motion of objects. For example, if you know the mass and velocity of an object, you can use the law of conservation of momentum to predict where it will go if it collides with another object.
