## Summary

Momentum…is a amount that defines an object"s resistance to protecting against (a type of "moving inertia").is represented by the symbol**p**(boldface).is the product of one object"s mass and velocity.

**p**=m**v**

**J**(boldface).is the product of the mean net pressure acting on an object and that duration.

**J**=**F**∆t

**J**=∆**p**

**F**∆t=m∆**v**

**F**dt=md**v**+**v**dm

*mass*(or thrust per mass circulation rate)is equal to exhaust velocity and also has the SI unit the meter per second.

*weight*(or thrust every weight flow rate)is same to exhaust velocity separated by acceleration due to gravity and has the SI unit of second.
