Unbalanced forces cause accelerations.
In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting upon an object are balanced or unbalanced, an analysis must be conducted to verify what forces are acting upon the object and in what direction. If two individual forces are of equivalent magnitude and opposite direction, the forces are balanced. An object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of euqivalent magnitude and in the opposite direction
Copper losses: These losses occur because of ohmic resistance of the transformer windings. If I1 and I2 are primary and secondary currents correspondingly and R1and R2 are the res
Magnetic poles: The two regions near the ends of a magnet at which the attracting forces appear to be concentrated are called the magnetic poles. The pole (when freely suspende
What are parallel forces?
The opposition offered to the circular motion of bodies like sphere, disc, ring, cylinder etc. on another surface is known as rolling friction.
