Gravity is a force. By the way, it is an action-at-a-distance force. How would you answer the question: What is the connection between the gravitational force and weight? Teacher

Actualy not much. It does pull things down but they are not affected by it becouse of weight. In vacum a feather falls at the same speed as a heavy stone. In our atmosphere there is air friction, wich make the diference in falling speed of feather and stone. I am not sure at this time, if I am right but I think it is this way.
I don't quite agree with Gregor. Connection between weight and gravitation is quite obvious. I will give an example: if gravitation on the Earth would be twice as large as it is, then things would weight twice as much also. That's why you would weight much more on planets with larger gravitational force. I agree with Gregor in other part, but I still think that Gregor has confused mass and weight, that's why he said actually not much.
I am glad you are here. This means that you are doing some extra English work at home. Our blog is just another way of communication between us. My plan is to post tasks here for you from time to time. It will not take much of your free time, but I hope it will help you improve your command of English. Your commitment will also be awarded according to our agreement at school. I want you to communicate in English. Do not forget to be polite and always sign your comment with your code; "anonymous" posts are not welcome. Teacher

It is simple, the more you weight, the faster you fall down!
Is it always the same - the more you "weigh", the faster you fall down?
Force is an influence that may cause an object to accelerate. It may be experienced as a lift, a push, or a pull.
So an interesting question ''how would the world look like when there were no forces?''
:)
The question was there and you were supposed to read and answer it.
