• Gravitational

• Electromagnetic

• Strong Nuclear

• Weak Nuclear

Fundamental Forces- Weakest, attractive, affects anything with mass, long range (infinite)

- 2nd Strongest, attractive/repulsive, affects anything with charge/magnetic properties, long range (infinite)

- Strongest, attractive, holds nuclei together, short range (within the nucleus)

- 3rd Strongest, neither attractive or repulsive, changes nucleus, short range (within the nucleus)

Fields

• An invisible agent for transmitting a force across empty space

• Allows for action at a distance
