What is force?
Force is defined as push or pull acted on an object. There are two classifications of
forces: contact force and non-contact force.
Contact forces are forces which involve two objects physically interacting or touching
each other.
Non-contact forces are forces that act between two objects that do not require
physical interaction.
Types of forces
The table below explains and illustrates the different types of forces.
CONTACT FORCES
1. Air-resistance force
The force acting on objects traveling on air.
EXAMPLE ILLUSTRATION
2. Tension force
The force transmitted along a string, cable,
rope, or a wire when pulled by an object to the
opposite side of the string.
3. Spring force
The force exerted by a stretched or compressed
spring on an object that is attached to it.
4. Normal force (reaction)
When one force is exerted on another body (A),
the second body (B) exerts force perpendicular
to the surface of the first body (A).
5. Applied force
The force exerted by an object or a person (A)
to another object (B) by physical contact.
