Types of Forces and Force Representation
The Gravitational Force
A force between two objects with mass
Very weak unless one object is very massive.
Pulls each object toward the other along the line connecting their centers
The Electromagnetic Force
Electromagnetic force exists between two objects with electric charge
Can be attractive or repulsive
Positive and negative charges
Opposite charges produce an attractive force
Same charges repel each other.
The Strong and Weak Nuclear Forces
Involve holding atomic nuclei together and radioactive decay
Most noticeable forces are gravitational or electromagnetic
Macroscopic Forces
Involved in nearly every interaction we experience in daily life
Occurs when surfaces rub together or liquids/gases flow past objects
When an object rests on a horizontal surface, the surface pushes back upward as an electromagnetic interaction
When a string or rope pulls on an object, creating a chain of electromagnetic interactions
Force Notation
F represents force.
Subscripts indicate the type of interaction:
g for gravitational force,
f for frictional force,
T for tensional force,
⊥ for normal (support) force,
A for any other generic applied push or pull.
