Question

which of the following pairs shows the correct grouping of positive and negative for the direction of forces?
left/down = positive, up/right = negative
left/down = negative, up/right = negative
left/down = positive, up/right = positive
left/down = negative, up/right = positive

Explanation:

In physics (a sub - field of Natural Science), when dealing with forces in a coordinate system (commonly used in force analysis), the right and up directions are often taken as positive, and the left and down directions are taken as negative. This is a common convention in vector analysis related to forces.

Answer:

Left/Down = Negative, Up/Right = Positive
