It may have something to do with the fact that the gravitational pulls are proportional to the masses of the earth and your teacher and that your teacher has considerably less mass than the earth!
Theoretically it's independent, but often in practice you just weigh something and convert.

The difference lies in the mass and distance between you and your teacher. Earth is much more massive and closer to you than your teacher, so its gravitational force is much stronger. Additionally, the force is proportional to the mass of the objects involved, therefore Earth's gravitational pull has a more noticeable effect on you compared to your teacher's.
The moon has a greater effect than the sun on the earths oceans.
Earths rotation around its axis
The gravitational forces of the Sun and Moon, effect the earths oceans by forming tides.
The centre of the earth is solid iron, however the centre of the earths gravitational pull changes, due to the movement of the moon, which has an effect on the earths gravity.
Earth's gravitational pull causes the ball to fall back down to the ground after being tossed. The strength of the gravitational pull determines how quickly the ball falls and how high it can be thrown.

The moon's gravitational pull creates tides on Earth's surface water. As the moon orbits, its gravitational force causes water to bulge out toward the moon, creating high tides. This effect is more noticeable in areas closer to the moon.

All of the earth's motion is completely determined by gravity: the gravitational pull on the earth by the sun (and the larger outer planets), the gravitational pull of the Milky Way galaxy on the sun, the gravitational pull of our local cluster on the Milky Way galaxy and so on, up the ladder.
One disadvantage of gravitational force is that it becomes weaker as distance between objects increases, leading to a decrease in its effect over long distances. Additionally, gravitational force is always attractive and cannot be repulsive, which limits the range of interactions it can facilitate.
The sun effects the Earth because of the particles that get thrown out into space can interact with the Earths atmosphere and effect it. The moon has a gravitational effect on Earth and so makes the tides in the ocean happen. There are many other reasons!

The greenhouse effect is when gases get trapped inside the earths atmosphere and cannot get out so the sun heats them up and the earth gets warmer. just like a greenhouse
