Gravity acts on all objects with mass. In the context of the Earth, gravity mostly acts on the Earth itself and objects on or near its surface.
This depends greatly on the objects. I assume you know that the electrons that surround all atoms are what prevents any two objects from making contact. So hypothetically, if you could get two soccer balls to "touch," by the time they got within a femtometer of each other, you will have built up so much potential energy in the magnetic field between the two soccer balls that once you pushed it any further, all the energy would be released and the balls would go flying at a very high speed in opposite directions.
it is too big
So he could come up with the ball drop theory, which is that all objects drop at the same speed. Regarding the fact that one object has a much greater mass than the other object, it will still land at the same time. Hope this helps :)
It's easy friend , You have 3 ways . I'll tell you d simpler 2 ways . 1) Take a thermocol . Make balls ou of newspaper . Cut the paper ball into half and tape it nicely to allow it not to move . Then stck it nicely on a cardboard or thermocol acc to ur convenience . 2)take small balls instead of newspaper balls . It's easy . I don't know what a thermocol is, but you can make a model with anything round, not just balls of newspaper. You can use different sizes of candy, or styrofoam balls, or even different sizes of sports balls and marbles - anything round will do. You can mount them onto a flat background like a poster or use wires to make a hanging model.
AnswerThe first sports balls were made with leather or pigskin.
One can purchase Titleist Pro V1 golf balls in the United Kingdom from sports stores such as Nike or Source for Sports. One could also purchase them from the official website, Amazon or eBay.
Balls have no nerves, they are inanimate objects.

Squash balls can be purchased online through a variety of websites such as Amazon and Sports Chalet. Squash balls are also available at many local sports and athletics stores such as Sports Authority or Academy Sports.
A basketball and a globe could be some types of spheres. Orange, soccer ball, marbles, planets, tennis balls, and other balls I guess.
Some objects that use compressed air include pneumatic tools (such as nail guns and air compressors), inflatable objects (such as tires and sports balls), pneumatic systems in vehicles, and air cannons in entertainment and industrial applications.
You could try asking at a sports shop, if they don't sell them, they could probably give you an address of where you can. Failing that you could try ebay.
