The force acts in all directions on the particle due to the fluid pressu...
The key factor responsible for force is the interaction between two objects.
Force is a push or pull that can cause an object to accelerate or deform.
The key factor responsible for force is the interaction between two objects.
Force can be exerted through direct contact (contact force) or without direct contact (field force).
Examples of forces include gravity, friction, electromagnetic force, and applied force.
