Abbreviation: Fpress
Friction
The force between two surfaces that works against motion
Abbreviation: Ff
Air Resistance

Abbreviation: Fn
Tension/ elastic
A force caused by string, spring or rope resulting in strerching or pulling
Abbreviation: Fr, Fel

Gravity
Weight is the force with which gravity attracts an object towards the earth. therefore, we consider weight as the gravitational force.
