Forces which are parallel and acting in same direction are called like parallel forces.
Forces which are parallel and acting in opposite direction are called unlike parallel forces.

Like parallel forces have the same direction and magnitude, resulting in a net force along the same line. Unlike parallel forces have different directions or magnitudes, leading to a net force that is not aligned with the forces.
LIKE PARALLEL FORCES are the forces that are parallel to each other and have same direction.
UNLIKE PARALLEL FORCES are the forces that are parallel to each other and have opposite direction.
Like parallel force are parallel to each other and have same direction while unlike parallel forces are parallel and have opposite direction
Line of action of force is same in like parallel force while unlike parallel forces have different line if action of force
Forces which are parallel and acting in same direction are called like parallel forces. Forces which are parallel and acting in opposite direction are called unlike parallel forces.
Examples of unlike parallel forces include lifting a box with one hand while pushing it with the other, or pulling a wagon from opposite directions with two ropes. These forces have different magnitudes and act in opposite directions along parallel lines.
You can calculate the total force in a system of parallel forces by adding up all the individual forces acting in the same direction. Simply sum the magnitudes of the individual forces to find the total parallel force.
To find the resultant of two unlike and unequal parallel forces acting on a rigid body, you can use the parallelogram method. Draw a parallelogram with the two forces as adjacent sides, then draw the diagonal from the point where the two forces intersect. The resultant force is represented by this diagonal and can be calculated using the magnitude and direction of the forces.
The resultant torque of a couple is the vector sum of the individual torques produced by the two equal and opposite forces that make up the couple. It is the product of the force magnitude and the perpendicular distance between the forces. The resultant torque of a couple is constant and does not cause linear acceleration but only rotational motion.
