What else can I help you with?
Why you calculate momentum?
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.
How can hydroelectric energy be used efficiently and or conserved?
Power generated by hydroelectric means is no different than power produced by any other means. The only way to demonstrate efficiency and conservation of energy is by keeping the lakes above the dams full of water.
What is gross thrust in a turbine engine verses net thrust?
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.
What are pump fundamentals?
Pump fundamentals are the fundamental principles that govern how pumps work. These include the conservation of mass, mechanical energy, and momentum which is often restated in the form of the Bernoulli equation:(P2-P1)/rho+g*(z2-z1)+0.5*(V2^2-V1^2)+ef+w=0for incompressible systems in turbulent flowP2= outlet pressureP1= inlet pressurerho= densityg= gravitational constant = 9.81m/s^2=32.174ft/s^2 on earth at sea levelz2= final heightz1= initial heightV2= outlet velocityV1= inlet velocity (often equal to zero if you are pumping a stationary fluid)ef= frictional force (summation of all friction due to pipe lengths, fittings, valves, expansions, and contractions)w= work (in this case w>0 means work flows out of the system)The continuity equation is useful when dealing with flowing fluids and is simply a restatement of conservation of mass:(rho*V*A)in=(rho*V*A)outA= cross sectional area
How do you spell build in french?
it means "construi" but construi not means to build it means construct
How does the conservation of angular momentum relate to the conservation of linear momentum in a physical system?
The conservation of angular momentum and the conservation of linear momentum are related in a physical system because they both involve the principle of conservation of momentum. Angular momentum is the momentum of an object rotating around an axis, while linear momentum is the momentum of an object moving in a straight line. In a closed system where no external forces are acting, the total angular momentum and total linear momentum remain constant. This means that if one type of momentum changes, the other type will also change in order to maintain the overall conservation of momentum in the system.
How does the conservation of linear momentum relate to the conservation of angular momentum in a system?
The conservation of linear momentum and angular momentum are related in a system because they both involve the principle of conservation of momentum. Linear momentum is the product of an object's mass and velocity in a straight line, while angular momentum is the product of an object's moment of inertia and angular velocity around a point. In a closed system where no external forces act, the total linear momentum and angular momentum remain constant. This means that if one form of momentum changes, the other form may change to compensate, maintaining the overall conservation of momentum in the system.
How does the conservation of angular momentum influence the expected spin of planets?
The conservation of angular momentum affects the expected spin of planets by causing them to rotate at a relatively constant speed as they orbit the sun. This means that planets are likely to have a consistent spin rate over time due to the conservation of angular momentum.
How do solve conservation of angular momentum?
Usually you would use some fact you know about the physical system, and then write an equation that states that the total angular momentum "before" = the total angular momentum "after" some event.
How can the conservation of angular momentum be ensured in a system, and what condition must be met for this conservation to hold true?
The conservation of angular momentum in a system can be ensured by making sure that no external torques act on the system. This means that the total angular momentum of the system will remain constant as long as there are no external forces causing it to change.
What is torque when angular momentum is constant?
When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
What causes a top to right itself when it spins?
Conservation of angular momentum means that the top will stay in the same orientation it was started in while spinning, which is not necessarily upright. Gyroscopes for instance can be started at an angle of 45o to the ground and will remain at that angle as long as they keep spinning.
What happens to the angular speed of a star as it shrinks?
As a star shrinks, its angular speed typically increases due to the conservation of angular momentum. This means that as the star's radius decreases, its rotation rate speeds up in order to conserve the total angular momentum of the system.
If something shrinks in size but not in mass what happens to its angular momentum?
Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster.Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body.

How does mass affect angular momentum?
Short answer: Angular momentum is proportional to mass. If you double the mass of an object, you double its angular momentum.Long Answer:Angular Momentum is a characteristic of rotating bodies that is basically analogue to linear momentum for bodies moving in a straight line.It has a more complex definition. Relative to an origin, one obtains the position of the object, the vector r and the momentum of the object, the vector p, and then the angular momentum is the vector cross product, L.L=r X p.Since linear momentum, p=mv, is proportional to mass, so is angular momentum.Sometimes we speak of the angular momentum about the center of mass of an object, in which case one must add all of the bits of angular momentum for all the bits of mass at all the positions in the object. That is easiest using calculus.It should also be said that the moment of inertia, I, is proportional to mass and another way to express angular momentum is the moment of inertia times the angular velocity.
Why does the world pivot on its axis?
The world spins around because of the way the solar system was formed as a spinning cloud of matter. This then it began to collapse in on itself as it did this the heat at the centre became so great that the sun ignited and pushed out all the matter which then formed the planets, still spinning because of the energy from the explosion as the sun ignited.Supplement 2 As far as the planets are concerned, they would have had some net rotational momentum, the residual of all the components that made the planet.This rotational energy cannot be destroyed - it however might be cancelled out by opposite-spin material.BUT back to the question. The Earth carries the residual net spin from its assembly from space debris.Answer:The rotation comes about from the conservation of angular momentum. The formula for angular momentum is:L=mwr2m is the mass,w is the angular velocity in radians per second, andr is the radius of the circular motion.Due to conservation of angular momentum, as the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). As a consequence the parts of the planet closer to the primary (the Sun) must rotate faster than the parts furthest from the Sun. This causes the spin.This all relates to the fact that planetary and stellar systems are born from the collapse of dense interstellar clouds. As the clouds collapse even a small rotation is magnified by the contraction. If the clouds were not rotating (matter fell straight to the center of the system) there would be no planets.
What is the relationship between the direction of angular momentum and the motion of a rotating object?
The direction of angular momentum is always perpendicular to the axis of rotation of a rotating object. This means that as the object rotates, its angular momentum will also change direction, influencing its motion and stability.
