Answer:
in general the largest mass M is located at the origin of the coordinate system.
Explanation:
The law of universal gravitation is
F = G m M / r2
Newton's second law is
F = m a
Where the acceleration is centripetal
a = v² / r
Let's replace
G m M / r² = m v² / r
M = v² r / G
The value of r is the distance between the two masses in interest, in general the largest mass M is located at the origin of the coordinate system.
This is because the body with more mass moves less than the body
Answer:
Momentum is always conserved, and kinetic energy may be conserved.
Explanation:
For an object moving on a horizontal, frictionless surface which makes a glancing collision with another object initially at rest on the surface, the type of collision experienced by this objects can either be elastic or an inelastic collision depending on whether the object sticks together after collision or separates and move with a common velocity after collision.
If the body separates and move with a common velocity after collision, the collision is elastic but if they sticks together after collision, the collision is inelastic.
Either ways the momentum of the bodies are always conserved since they will always move with a common velocity after collision but their kinetic energy may or may not be conserved after collision, it all depends whether they separates or stick together after collision and since we are not told in question whether or not they separate, we can conclude that their kinetic energy "may" be conserved.

Its an example of a universal law because gravity occurs in every place of the world
Hoped I helped!!!!!
