Q. Illustrate what path does an asteroid take?
Answer:-
The asteroid will forever take the path minimizing its Lagrangian recognized as the least action principle in Lagrangian mechanics. With conservative forces there are four fundamental shapes for two different cases either the asteroid is trapped in the gravitational pull of an object or it is not trapped. If the asteroid's energy is little enough to be trapped then it can have either a circular or elliptical orbit. If it isn't trapped then this free asteroid (much like a free electron) can have either a parabolic or a hyperbolic path. A lot of this information came from Classical Mechanics by kibble and Berkshire even though there are much better books.

what is sound wave
Consider two identical plastic foam balls each one having a thin sheath of aluminium foil. One of the balls has a few positive charges and the other has the same amount of negative
Q. If the moons orbit is inclined somewhat relative to the Earth's orbit what effect does this have on eclipses? Answer:- This makes eclipses rarer as well as if the moon's
MOTION: A body is said to be in motion if it alters its position with respect to its surroundings.
working model needed.........please help!!!!!!!!!!!!
Q. Show Constant Moment Arm? The simplest case is that of a point mass, and the moment of inertia can be immediately written as I = mR 2 ,
The magnifying power of an astronomical telescope in the normal adjustment position is 100. The distance among the objective and the eye-piece is 101 cm. Measure the focal lengths
the principle
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
