momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
Momentum=mass x velocity
Mass is measured in kilograms
Velocity is measured in metres per second per second (ms-2 or m/s/s)
Momentum measures the amount of potential energy that is acting on or can act on an object. By calculating momentum physicists can determine the destination of an object by simply comparing its mass and how fast it is going (according to acceleration and negative acceleration (or deceleration)).
You are wrong
angular momentum is the measure of angular motion in a body.
When the spacecraft is an equilibrium state, if the spacecraft has a momentum for specific axis, then the control of spacecraft is designed to momentum bias method. if else, it is called a zero momentum spacecraft. Zero momentum spacecraft: a spacecraft has four reaction wheel which is installed to pyramid configuration. if1st and 3rd reaction wheel is running to a 500 rpm and 2nd and 4th reaction wheel is running to a 500 rpm, them totoal net momentum is a zero.
angular momentum = linear momentum (of object) x perpendicular distance (from origin to the object) where x stands for cross product. angular momentum = mv x r (perpendicular dist.)
Hi there, Gross thrust is the reaction of the momentum of the jet stream produced in a gas turbine engine.If you don't know net thrust,let me tell you.Net thrust is the resultant force acting on the aircraft.Net thrust=Gross thrust-Momentum(Intake)Drag.Don't go deep in momentum drag.When the aircraft with turbine engine,is moving...Gross Thrust is more than net thrust.and when the engine is at the rest,gross thrust=net thrust.Hope you got the answer.....Good luck in your future.

Gross thrust, means the thrust when there is not forward momentum of the jet. However, the jet has always the forward speed. When we consider this, we can calculate the net thrust as the gross thrust minus the forward momentum.
An object's momentum depends on its mass, its speed, and the direction it's moving. If you know these numbers, you can calculate the momentum on your own. You don't need no scientist.

The momentum before and after is the same, due to the Law of Conservation of momentum. Thus if you calculate the momentum before, then you have the after momentum or vice-versa.
change in momentum
Momentum (p) is mass (m) times velocity (v), so p = mv

J=(2/3)mr^2
impulse= the change in momentum or force multiplied by time
(1) Decide on a direction that you will consider positive. (2) Calculate the momentum of the object that travels in the "positive" direction. (3) Calculate the momentum of the object that travels in the "negative" direction (the momentum should be negative). (4) Add both numbers algebraically.
You may see acceleration mentioned in a momentum problem; but if it's there, it's only purposeis to help you find the object's velocity.All you need to know in order to find momentum is the object's mass and velocity.
The idea is to use conservation of momentum. Calculate the total momentum before the collission, add it up, then calculate the combined velocity after the collision, based on the momentum.
In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg ยท m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.
