If an oscillating object is subjected to small impulses of the same frequency as the object's natural frequency of oscillation, its amplitude will build up rapidly, depending on how much damping is present. This is caused resonance.
Amplitude of oscillation is the maximum displacement of a vibrating or oscillating object from its equilibrium position. It represents the maximum distance the object moves from its resting position during one complete cycle of motion.
It it called balanced forces.
Resonance - when pumping a swing in rhythm with its natural frequency, it produces larger amplitudes.(def. - occurs when the frequency of a vibration forced on an object matches the object's natural frequency and a dramatic increase in amplitude occurs)
In an electromagnet, the magnetic forces increase as the current flowing through the coil increases. This is because the magnetic field strength is directly proportional to the amount of current flowing through the coil.
The result of unbalanced forces is called acceleration. When the forces acting on an object are unbalanced, the object will accelerate in the direction of the stronger force.
Amplitude of oscillation is the maximum displacement of a vibrating or oscillating object from its equilibrium position. It represents the maximum distance the object moves from its resting position during one complete cycle of motion.
In space, objects move steadily due to inertia, which is the tendency of objects to continue moving in a straight line unless acted upon by an external force. Without air resistance or other forces to slow them down, objects in space will continue moving steadily on their own inertia.
Forces that cancel each other out are called balanced forces.

These forces are called adhesion forces.
In an electromagnet, the magnetic forces increase as the current flowing through the coil increases. This is because the magnetic field strength is directly proportional to the amount of current flowing through the coil.
Actually, forces that are equal in size but opposite in direction are called balanced forces. Unbalanced forces are forces that are not equal in size and/or opposite in direction, resulting in a change in an object's motion.
To decrease the forces that opposes motion
all such forces are intermolecular forces.
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
