👉 Momentum is a vector quantity that combines both velocity and mass, describing an object's tendency to keep moving in the same direction it was going. Mathematically, momentum (p) is defined as the product of an object's mass (m) and its velocity (v), expressed as p = m
v. This concept is crucial in physics, especially when analyzing collisions and motion under forces, as it helps predict how objects will behave over time based on their initial conditions. The direction of momentum aligns with the object's motion, making it a powerful tool for understanding and calculating the dynamics of moving systems.
