Reaction force direction during reflection

In summary, the direction of the reaction force exerted on the wall will be determined by the change in momentum of the object before and after the reflection. This change can be seen in both the horizontal and vertical momentum, and it will determine the force direction.

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)

Neither.
 
  • #3
So what will be the direction of reaction force?
 
  • #4
How did the momentum of the object change from before to after the reflection?

To add to olivermsun, look specifically at the change in the horizontal momentum and the change in the vertical momentum. What does that tell you about the force?

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?

Yes, if the green arrows represent the momentum vectors of the object, before and negated after the collision.

It depends on how the momentum of the object changes, just as your diagram shows.
 

1. What is reaction force direction during reflection?

Reaction force direction during reflection refers to the direction in which an object or surface pushes back against an applied force during a reflection. This force is equal in magnitude and opposite in direction to the applied force.

2. How is reaction force direction determined during reflection?

The reaction force direction during reflection is determined using Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. This means that the direction of the reflection force is always opposite to the direction of the applied force.

3. Does the angle of incidence affect the reaction force direction during reflection?

Yes, the angle of incidence does affect the reaction force direction during reflection. When the angle of incidence is increased, the angle of reflection also increases, which results in a change in the direction of the reaction force.

4. How does the surface affect the reaction force direction during reflection?

The surface does not affect the reaction force direction during reflection. The reaction force will always be equal and opposite to the applied force, regardless of the surface on which the reflection occurs.

5. Are there any real-life applications of understanding reaction force direction during reflection?

Yes, understanding reaction force direction during reflection is important in fields such as optics, acoustics, and mechanics. It is also crucial in sports such as billiards and tennis, where understanding the direction of the reflection can help players predict and control the trajectory of the ball. Furthermore, in engineering and construction, knowledge of reaction force direction during reflection is essential to ensure the stability and safety of structures.
