8. Translate the following sentences and explain the use of tenses in them:
1. One of Newtion's great discoveries was that all massive objects exert forces of attraction on each other. 2. These forces are called gravitational forces. 3. The gravitation pull or force which the earth exerts on any object is given a special name. 4. It is called the weight of that object. 5. The weight always acts downwards, towards the centre of the earth. 6. If no other forces hinder it, any object will therefore be pulled as close to the centre of the earth as it can get, i.e., it will fall to the ground. 7. Newton discovered that the pull of the earth on an object, i.e. the weight of an object, is directly proportional to the mass of the object.
