Answer:
Equinox
Explanation:
It is an astronomical phenomenon that is repeated twice a year, in summer and winter, and that is caused because the axis on which our planet rotates is slightly inclined with respect to the plane of translation, this is its trajectory around the Sun.
For this reason there are two equinoxes a year, a phenomenon completely opposite to the solstice, but also marks the beginning of the spring and autumn seasons.
The equinoxes occur around March 20 or 21 and September 22 or 23, and it is the days when the Sun is exactly over the equator, which makes day and night more or less the same duration. The word ‘equinox’ comes from Latin and means precisely ‘same night’. In those two moments the part of the Earth closest to the Sun is the equator.

because an object need to be in motion to make any kind of movement
No
Explanation:
Average speed of car = 5m/s
Distance run by dog = 20m
Time taken = 5s
problem;
does the dog catches the car = ?
Solution;
let us determine speed of the dog;
Speed = 
= 4m/s
The average speed of the car is 5m/s
Average speed of the dog is 4m/s
The dog is slower than the car and it will not catch the car at this rate.
