Fundamental Forces

Fundamental forces There are 4 fundamental forces in nature: 1. 2. 3. 4. Gravity Electromagnetic Weak nuclear Strong nuclear

Gravity relative strength = 6 x 10 -39 range = infinite Gravity is an attractive force between all matter in the Universe. The more mass something has, the larger the net gravitational force is. Gravity is the most important force over large scales since positive and negative charges tend to cancel.

Electromagnetic relative strength = 1/137 range = infinite Between charged particles The electromagnetic force can be repulsive (+, + or -, -) or attractive (+, -). Normal chemical reactions are governed by this force.

Weak Nuclear relative strength = 10 -6 range = 10 -10 meter The weak force governs beta radioactive decay reactions.

Strong Nuclear relative strength = 1 range = 10 -15 meter The strong force holds atomic nuclei together. Nucleons and quarks

Standard SC. 912. P. 10 Compare the magnitude and range of the four fundamental forces (gravitational, electromagnetic, weak nuclear, strong nuclear). identify which forces would have the greatest impact to a given scenario, i. e. , holding a planet in orbit (gravity) holding a nucleus together (strong) keeping atoms from moving into one another, i. e. superposition (electromagnetic)
