OR

Define like and unlike parallel force?

Difficulty: Easy

Difference between like and unlike forces:

 

Like parallel Force

Unlike parallel, force like

Like parallel forces are the forces that are parallel to each other and have the same direction unlike

Unlike parallel forces are the forces that are parallel but have directions opposite to each other. 

Explanation:

The forces F1, F2, and F3 are acting at points A, B, and C respectively.

Since the direction of the applied forces F1, F2 and F3 are the same, these are like parallel forces. The applied forces F1, F2, and F3 are acting in the opposite direction, so these are unlike parallel forces.
