The discussion revolves around the physics of a ball bouncing off walls in a Unity game environment. Participants explore the equations governing the ball's motion, particularly focusing on speed, angles of incidence and reflection, and the effects of gravity on the bounce behavior.
Participants generally agree on the conservation of speed and the relationship between the angles of incidence and reflection. However, there is some confusion regarding the implications of ignoring gravity and how it affects the ball's behavior post-bounce, indicating that the discussion remains unresolved.
The discussion assumes a simplified model of motion that neglects gravitational effects, which may not reflect real-world physics. The implications of this assumption on the ball's trajectory and bounce behavior are not fully explored.
Ah I see so how would i get the speed of the ball coming off the wallRUber said:Since speed is conserved, you are ignoring gravity too?
Any bounce should maintain that the angle a made with the wall coming in will be the same as the angle leaving the wall.
In 2d, that means if approach angle =a, departure angle = 180-a.
a=0 describes rolling. a=90 is a straight on bounce and return, ie normal incidence.
Sorry not speed how far will it bounceRUber said:You said the speed doesn't change.
If you are ignoring gravity (as you must be in order to have constant speed), it will continue after the bounce until it hits the next wall.Alexander Baine said:Sorry not speed how far will it bounce
