In introductory physics, when you are asked to solve gravity problems including free fall, you are asked to ignore the effects of air resistance. In practice, these effects are considerable, as you will learn if you pursue engineering or a similar field. ...
In physics, a kind of force by which two objects of certain mass are drawn towards each other is described as the gravity force. The higher value of the length of space among two objects lowers the value of the gravity force.Answer and Explanation: ...
