Force is any influence which tends to change the
motion of an object.
A force has both magnitude and direction,
making it a vector quantity. It is measured in
the SI unit of Newton and represented by the
symbol F.
The forces are balanced when things are notmoving.
When the forces are not equal, they are calledunbalanced forces.
A contact force is the one which acts at the point of contact between two objects.
A non-contact force is a force applied to an object by another body that is not in direct contact with it.
