Represent in a vector diagram: A man applying an 80N force on a block in a direction towards the south

To represent the 80N force in a vector diagram, follow these steps: 1. **Draw an Axes**: Start by drawing a set of Cartesian axes. The vertical axis will represent north and south, while the horizontal axis will represent east and west. 2. **Indicate Directions**: Label the directions on the axes. The upward direction on the vertical axis is north, and the downward direction is south. The right side of the horizontal axis is east, and the left side is west. 3. **Draw the Force Vector**: From the origin of the axes, draw a straight arrow pointing downwards since the force is directed towards the south. 4. **Label the Vector**: Make the length of the arrow proportional to the magnitude of the force (80N). You can choose a scale, for example, 1 cm = 20N. Therefore, the arrow would be 4 cm long to represent an 80N force. 5. **Add a Label**: Next to the arrow, write "80N" to indicate the force magnitude and its direction. This diagram clearly shows the direction and magnitude of the force that the man is applying to the block.
