... Answer. Kepler was not aware of the law of inertia, or at least didn't apply it to this situation. The cannonball at rest in the cannon has the same speed as the earth's surface at that point. Its firing speed is relative to the moving earth, so there would be practically no difference in range whet ...

For example, in the carom board game we sprinkle powder to reduce the frictional force between the coins and the wooden board. This helps the coins to move faster than on an unpowdered boar ...

... In the absence of external forces, an object at rest remains at rest and an object in motion continues in motion with a constant velocity. What does this statement tell us? 1. When no force is exerted on an object, the acceleration of the object is 0. 2. Any isolated object, the object that do not i ...
