Is Acceleration due to gravity independent of horizontal velocity?
acceleration from gravity is a constant, while the velocity is the speed the object is traveling at. All objects regardless of mass will reach the graound at the same time as long as the following are applicable: 1. wind resistance for both is identical (a piece of paper has more wind resistance than a bowling ball 2.the ammount of lift generated by the objects is the same (a paper airplane will hit the ground later because when it reaches a certain speed it levels off) and 3. the forces reacting on the objects are identical (if there is wind pushing one object down and not the other the one will fall faster. For the bullet question, the bullets would land in the same time frame, but bullet a will travel very far forward in that time. neither would have a downward velocity at start and so their downward acceleration and their downward velocity when dropped or fired would be the same. and would thus fall the same distance vertically in the same ammount of time although total distance tr
Yes and No. The bullet fired horizontally will have some horizontal force on it and hence it would go horizontal first before going vertically down. Gravity is independent of horizontal velocity only in true and perfect condition. Hence, in vacuum. So if you drop a feather and bullet from the same height in vacuum. They will hit the ground at the same time.
