The sun ☀️
Why do we have day and night ?
Because the earth spins on its axis and one side is facing the sun (day )and the other side is not facing the sun (night )AND IS FACING DARKNESS.

Is the difference between the two forces acting in the opposite direction of the object .
Why are racing car 🏎 flat and smooth
To reduce air 💨 risstance
