Q10 of 21 Page 16

Find net forces from the following diagrams.

As we need to calculate Fnet and we know that force is a quantity possessing magnitude and direction ,so, we need to consider the directions also with the numeric values of the forces applied on the blocks.


The forces in opposite directions are to be subtracted from each other and the forces in same direction or parallel are to be added to each other. The resultant force will be in the higher magnitude force direction.

If you push a heavy box which is at rest, you must exert some force to start its motion. However, once the box is sliding, you can apply a lesser force to maintain that motion. Why?
