Reflection and force direction Let's say object hits a wall. When the object is reflected does the direction of the force caused on the wall looks like the red arrow ? Does that direction depends on how "strong" object is reflected?

So what will be the direction of reaction force?

I have a simple question let's say object hits the wall at angle and reflect. Will reaction force from that impact exerted on wall be red line or green line ? ( I would like explanation why in each case)

Let's say u sit in front of a fan. In a fan like that if I am not wrong it is moving in the right direction (clockwise). By the shape of blades I assume they create high pressure on a side closer to you but it would mean air would travel backward to a side further away from you (from high...

If fan blades move in a circular way how is the air moving towards you (in front of fan) ? Also propeller and fan have different shapes, does it mean they work different?
