Why is direction important in momentum?

Surely it is self-evident that the velocity [math]\vec{v}[/math] of an object must have a direction. Firing a cannonball straight up does not produce the same result as firing it horizontally. read more

why is direction important in doing momentum problems. We use vectors because direction is important in doing things in real life. If an object is moving north, we need to push southwards to stop it; if an object is moving south, we need to push northwards to stop it. read more

To calculate the momentum of a moving object, multiply the mass of the object by its velocity. Momentum is also a vector. That means that momentum is a quantity that has a size and a direction; that direction can be either positive or negative. Momentum in Life. Momentum is one of the most underrated components of success. read more

Momentum is a valuable tool for predicting the future of physical systems. It joins the ranks of kinematics, forces, and energies. What sets momentum apart is that it’s a conserved vector quantity. read more
