Momentum: A vector quantity that represents the product of an object's mass and velocity, indicating both the magnitude and direction of motion.
Vector quantity: A physical property that has both size (magnitude) and direction.
Momentum as product of mass and velocity: The calculation of momentum involves multiplying an object's mass by its velocity, expressed as p = mv.
Momentum as measure of accelerating force over time: It quantifies the force needed to change an object's motion, either to accelerate from rest or to bring it to rest, over a specific time interval.
Momentum is calculated by multiplying an object's mass by its velocity, resulting in a vector quantity that possesses both magnitude and direction. It serves as a measure of the motion of an object and the force required to alter that motion. Specifically, momentum indicates the force necessary to accelerate an object from rest to its current speed and also the force needed to stop it, considering the time over which these changes occur.
