[OSS.01]Which of these statements is most likely correct about Newton's law on gravity?

Answer:
It does not explain why objects exert gravitational force.
Explanation:
As per the Newton's law of gravitation he said that two objects of different masses are placed at some distance from each other then the gravitational attraction force between two masses is
(1) proportional to the product of the two masses
(2) inversely proportional to the square of the distance between two masses
so it is given by
so here as per Universal law of gravitation Newton gives an experimental result about the gravitational force while the theoretical explanation why the gravitational force exist is not explained by Newton's law of gravitation
So correct answer will be
It does not explain why objects exert gravitational force.

<u>Answer:</u>
In an <u>inelastic collision</u> the kinetic energy is not conserved, but <u>the total momentum of the system is conserved</u>.
In other words; the Initial momentum is equal to the Final Momentum
:
Then:
<h2>
This means that after the collision the kinetic energy is transformed (dissipated) into another type of energy (caloric energy, for example); and there may be deformation in the blocks.
Therefore, the sentence that best describes this situation is:
<h2>The total momentum is zero. </h2>
