Earth is round in shape with gravity to pull down and is rotating, so how doesn't the man fall from the edge?

My son, studying in Class-3, raised this question that :

When the earth is round in shape like a ball, rotating and having gravity to pull down any object only ONTO it (but not from its surface), in that case, how can the man / object not fall down while on motion as anything (object) is placed on a real play-ball and the ball is slowly rotated by hand, that object will definitely fall down from the ball onto earth. Similarly, when the man himself is standing on the rotating earth which is also like a ball, how can the man or any object not fall from it?

Can you please answer this? However, my earlier question was of the similar type. But, I may be provided a comparison type of answer from 'Man on the Earth' to 'Object on a Play-Ball'.

Thanks & Regards,

V.Mallikarjuna Rao

Why does the force of gravity works on a car that rolls down hill, but doesn't work on a car on a level road?

Think: is the force of gravity always at work? is Newton's third law correct (For every action there is an equal and opposite reaction)? on a level road is the car reacting?

What do I do when a plant becomes dormant?

My plant is supposed to become dormant soon, and I don't know if I still have to take care of it. I also don't know when it will wake up from its rest and how I will know that it has.
