Force is a push or pull caused due to interaction between two objects.
There are mainly two types of force.
1)Contact force
Caused due to contact between two objects
example, muscular force,frictional force
2) Non Contact force
Caused when two bodies are not in contact with each other .
For example, gravitational force,magnetice force etc.
The SI unit of force is Newton ( N )
Pressure is the force exerted per unit area.
SI unit of pressure is Pascal ( Pa )
Friction is a contact force that stops moving things or prevents stationary objects from moving.
It is caused due to interlocking of irregularities present in two surface thereby, opposing motion.

force - any action which cause pull , hit or push on body is called force.
pressure- pressure is defined as thrust per unit area.
p=ft/A
