The conservation of motion is related to newtons #?? law?

Answer 1

Newt has several laws: one is for gravity and three are for motion as you put it.

Law 1: a body at rest or a body moving will stay at rest or moving at a constant velocity unless acted on by a net force (f).
Law 2: F = ma
Law 3: for every action there is an equal and opposite reaction

In reality, they are all the same law, which is Law 1. Why? Because mv = P; where m is the mass and v is the velocity of that mass and their multiple is called momentum (P). The conservation of momentum (which is what I think you meant) says that P before an event (e.g., impact) is exactly equal to P after that event. That is, momentum is neither created nor destroyed by two billiard balls or two atoms colliding for example.

Law 2 is simply Law 1 after taking the first derivative of P with respect to time. Thus, dP/dt = d(mv)/dt = m dv/dt = ma because dv/dt = a = the acceleration of the mass, which is assumed constant in this case.

Law 3 simply combines Law 1 and Law 2 by noting that when a force acts on a mass and that mass does not move (i.e., it's at rest), the net forces (f) must be zero because, otherwise, from f = ma the mass would accelerate (move). So f = ma = 0 must be true if the mass is not moving. Example, you're sitting in your chair reading this...but you are not sinking into the Earth. Why? Because your chair is pushing back on your weight. Thus f = W - F = ma = 0 because W - F = 0; where W is your weight and F is the opposite force from the chair.

So the lessons learned are: its called the conservation of momentum P = mv, which simply means P is neither created nor destroyed by an impact for example; and Newt's three laws are really derivatives of the first law.

Answer 2

Newton's second regulation of action (f=ma) is especiaily sensible at the same time as designing effective rockets. To enable a rocket to climb into low Earth orbit, that is critical to attain a speed, in extra of 28,000 km consistent with hour. A speed of over 40,250 km consistent with hour, noted as get away speed, facilitates a rocket to go away Earth and go back and forth out into deep area. reaching area flight speeds calls for the rocket engine to attain the astounding action stress conceivable contained in the shortest time. In different words, the engine ought to burn a huge mass of gas and push the ensuing gas out of the engine as straight away as conceivable. The action of the rocket would properly be defined by technique of Newton's 0.33 regulation, for each action there is an equivalent and opposite reaction. In different words, at the same time as one merchandise exerts a stress on yet another merchandise, the second one merchandise exerts a stress of equivalent power contained in the option direction on the first merchandise.

Answer 3

Quantitatively 2nd Law.

Answer 4

My best friend is related to Isaac Newton,you know...the scientist.He's her great uncle.

Answer 5

i think its related to 1rst law of motion.
