The direction that the ball hits the paddle or the paddle hits the ball is not relevant. What is relevant is the direction of the force. It is the direction of the two forces that are equal and opposite. The angle of the ball doesn't enter into it at all.Sundown444 said:
The angle of the force matters. The angle of the ball or the paddle or whatever doesn't matter except insofar as it affects the angle of the forcesSundown444 said:
The angle between the 3rd law forces is 180°.Sundown444 said:

The angle formed between both force vectors must be always π, otherwise we will have a third resulting vector force.Sundown444 said:
Action and reaction forces are a pair of forces that occur when two objects interact with each other. The action force is the force exerted by one object on another, while the reaction force is the force exerted by the second object on the first object in response.
Action and reaction forces are equal in magnitude and opposite in direction. This means that the force exerted by one object on another is always equal in strength to the force exerted back on the first object by the second object.
The principle of action and reaction forces, also known as Newton's Third Law of Motion, states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs and that the two forces are acting on different objects.
Action and reaction forces do not cancel each other out and do not affect the motion of the same object. Instead, these forces act on different objects, causing them to move in opposite directions. This is why an object at rest will remain at rest unless acted upon by an external force.
The angle at which action and reaction forces are applied can affect the resulting motion. When the forces are applied at a right angle, the resulting motion will be perpendicular to the forces. However, when the forces are applied at an angle, the resulting motion will be a combination of both forces, known as a vector sum.
