What scientific concept is defined as the product of mass and velocity?

The scientific concept defined as the product of mass and velocity is momentum. Momentum is a vector quantity, which means it has both magnitude and direction. It is calculated using the formula ( p = mv ), where ( p ) represents momentum, ( m ) is mass, and ( v ) is velocity. This relationship highlights how an object's momentum increases with either a larger mass or a higher velocity, making it a crucial concept in physics, particularly in the study of motion and collisions. Understanding momentum is essential for analyzing scenarios such as vehicle crashes or sports, where the conservation of momentum is an important principle.

Erosion involves the process of wearing away surfaces, gravity refers to the force that attracts two bodies toward each other, and force is related to the interaction that causes an object to change its motion. While all these options are significant concepts in science, they do not define the specific relationship of mass and velocity that characterizes momentum.
