Momentum – Concept Overview
... Inertia (I): The tendency of an object in motion to stay in motion (as well as for a still object to stay still) ex. spaceship keeps moving after it gets blasted. Momentum (p): The product of an object’s mass(m)and velocity(vvector) so p=mv. Can be: – Linear: momentum of an object moving in a straig ...

For spheres and other regular shapes at low fluid velocities, the flow patterns and drag forces can be estimated from published correlations or by numerical calculations using the general momentum balance equations. ...
