Can someone please explain the process of a ball bouncing in terms of Forces?
First, it doesn't make sense to say that the normal force is greater than that of the upwards force. When the ball hits the ground and gradually starts exerting the force of its weight, the ground exerts the same equal force just in the opposite direction. The ball starts compressing and ultimately, when it reaches $0 \ \ m/s$, it stops.
Now, the common explanation here is that, due to this compression, the ball pushes back creating a bigger upwards force and hence an upwards acceleration but I think this explanation is simply false or not adequate enough. The ball, due to its compression, pushes the floor. Meaning the force downwards now is $F_g+F_e$ (Weight and the elastic force), from this then follows that the upwards force is exactly the same $F_g+F_e$ just in different directions. This implies that since there is no net force in the upwards direction, there should be no acceleration in the upward direction and thereby the velocity of the ball will stay at $0 \ \ m/s$.
Is it even possible to explain this without mentioning energy and momentum?
