Kamau and Yara are standing on an open plain. Kamau is holding a large, light, flat board perpendicular to the ground. The wind starts blowing directly at the side of the board that Kamau is facing. Assuming the wind is strong enough and Kamau does not change his grip, what happens to the board and why?
Provide a very brief response.
The wind exerts a force on the board that Kamau is holding. Since the board is flat and large, it has a substantial surface area for the wind to push against, and because it is light, it does not require much force to move it. The wind will likely push the board back, causing it to either move back in Kamau's hands or, if the wind is strong enough, it may be ripped out of his hands entirely and be carried away by the wind. This happens because the pressure of the wind applies a force on the board in the direction the wind is moving, and if the force is greater than Kamau's ability to hold the board in place, the board will move in the direction of the wind.
