A magnet's pull force is the force required to pull that magnet straight free vertically from a plate made out of any ferromagnetic material. Near Earth's surface, the weight equation gives a measure of the pulling force of gravity.
6 sty 2022 · What is gravity? Gravity is a pulling force (always a force of attraction) between every object in the universe (every bit of matter, everything that has some mass) and every other object.
30 lip 2023 · Gravity: A universal force. Four fundamental forces act upon us every day. The strong force and the weak force operate only inside the centers of atoms. The electromagnetic force rules objects...
