Is the Upward Force on a Bouncing Ball the Same as the Average Normal Force?

[issacnewton]

Hello

I just have some basic question about the bouncing ball. When we throw a ball on the gound,
there is usual force of mg downwards, but since the ball is bouncing, due to the change in momentum, the ground will exert an upward force on the ball. Is this upward force same as the average normal force when the ball is in contact with the ground ? I am trying to think of free body diagram of the ball while it is in contact with the ground before it bounces off.

thanks

The upward force IS the normal force at all times

so how would the free body diagram look like ? when the ball is in contact with the floor, we have mg downwards and the N upwards, which is force exerted by the floor on the ball because of change in momentum ? so we have just two forces acting on the ball , right ?

yes, there are only 2 forces on the ball.
