Velocity Times Mass. P m v. This can be a change in cross sectional area of pipe or a change of flow direction as in a turbine.
Sep 21 2020 F m vt where m. This can be a change in cross sectional area of pipe or a change of flow direction as in a turbine. Objects that have momentum are not necessarily being acted on by a force.
And I think thats why it is defined as mass times velocity which is a simple relationship between mass and velocity with momentum.
Force mass x velocity time mass x velocity time momentum time. Mass times velocity is defined as momentum symbol p. Part of the series. Acceleration change of velocity.
