The Sun's gravity also contributes to tides but its effect is about half that of the Moon's due to its greater distance.

Gravity is an attractive force that pulls objects towards the center of the Earth which is downward.

According to Newton's first law without the Sun's gravitational force acting as centripetal force Earth would travel in a straight line tangent to its orbit.

Around December 22nd the Northern Hemisphere is tilted farthest away from the Sun marking the winter solstice.

Weight on Moon = (mass × g_earth) / 6 = (1 kg × 10 m/s²) / 6 ≈ 1.67 N.

The Earth spins around an imaginary line called its axis which runs from the North Pole to the South Pole.

Leo representing a lion is a prominent constellation visible in the spring sky.

The Earth's rotation on its axis causes the cycle of day and night.

Gravitational force is strongest at sea level because this is the point closest to the Earth's center of mass.

Mass is a measure of the amount of matter and does not change based on location. Only weight changes with gravity.
