N the particular case of motion, a reference point is a stationary point in space. You can then measure the displacement of objects in space from this point. A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to.

A reference is critical because it determines how much motion has occurred. You can't determine how much an objected has moved if you don't know where it came from.

Briefly explain the two postulates of relativity, how they differed from classical physics, and why Einstein was led to propose
Ray Of Light [21]

Explanation:

The two postulates of special theory of relativity

Postulate 1: The law of physics are invariant under any of inertial frame of reference.

Postulate 2: The velocity of light is remains same in each ans every frame of reference and independent of relativity.

They are differ from classical mechanics that in classical mechanics there is no change in mass and length in relative velocity but in relativistic mechanics it changes.

These two postulates implements in phenomenon like time dilation , length contraction etc.

The vernal equinox is now just entering the constellation aquarius. In what constellation will it lie in the year a. D. 10000?.
Keith_Richards [23]

The vernal equinox in the year AD 10000 will lie in the constellation Scorpio.

Once every 25800 years a full cycle of precession is completed. There are 12 constellations which means it takes 25800 / 12 = 2150 years to move from one constellation to the next one. The order in which the vernal equinox moves from Aquarius is Capricorn, Sagittarius, Scorpio, Libra etc.

Now the year is 2022 AD where the vernal equinox just entered constellation Aquarius. In 4172 AD it would have entered constellation Capricorn, then constellation  Sagittarius in 6322 AD, then constellation  Scorpio in 8472 AD and then constellation  Libra in 10622 AD. This means that in 10000 AD it is still in constellation  Scorpio and yet to enter constellation  Libra.

Therefore, In the year 10000 AD, the vernal equinox will lie in the constellation Scorpio.
