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
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 is mean by consevation of momentum?
Conservation of momentum means the sum of Momentum is constant. Conservation of Momentum is the result of Conservation of Energy.
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.

What is ment by angular momentum and angular velocity?
Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.
What does conversation of momentum mean?
Conservation of momentum means that momentum is a constant and the change of momentum or force is zero.
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 consseveration?
Conservation has two definitions that I know of in this category. One is in scientific laws like conservation of angular momentum or conservation of energy. Conservation in this sense means that that element can't be created or destroyed. Conservation of energy, for example means that energy isn't created or destroyed, but rather it changes form (like from chemical energy to heat). The other conservation is like wildlife conservation which includes programs where people try to conserve the Earth's resources, wildlife, etc.
According to the law of conservation of in an isolated system the initial total momentum before a collision equals the final total momentum.?
momentum
What quantities are needed to calculate angular momentum?
"Rate of change" means that you divide something by time ("per unit time" or "per second"), so you would use the units of angular momentum, divided by seconds.I am not aware of any special name for this concept.
What does the law of the conservation of momentum mean?
It means that there is a quantity called momentum; the total quantity of which doesn't change.
How can you prove angular momentum is quantized?
Angular momentum is one of three distiguishing properties of motion. It being quatized means that it cannot continuously vary, it varies only in quantum leaps between two set values.
