Contact forces: objects are in contact with each other and exert forces on each other. Non-contact (field) forces: objects are not in contact with each other and exert forces on each other.
What are examples of non-contact forces?
Some of the examples of non-contact forces are:
- Gravitational force.
- magnetic force.
- Electrostatics.
- The nuclear force - (there are two types of strong and weak nuclear force).
Is a field a force?
Fields and forces
A field is the area around an object where it can exert a force on another object, usually without there being any contact between the objects. We can represent a field as lines showing the direction of the force experienced by another object in the field.
