When a stationery object is struck by a moving object, such as a golf ball hit by a golf club, does the stationery object instantly move when struck. Or does it have to accelerate from 0 mph to say, 32 mph. If so, there must have been a moment when it reached 16 mph, and before that 8 mph and 4 mph and so on. As you cannot keeping halving your speed forever, or can you, the question is (1) at what point does it stop being stationery and become moving and (2) what speed does it start off at?
As I have no training in physics I can only come up with two possible answers, (1) 0 mph is somehow a speed with the same characteristics as any other speed, or (2) this sounds really weird but here goes, time does not flow but pulses. One pulse the object is stationery, and in the next pulse it is moving, meaning nothing exists between pulses in a time sense.
Looking at it another way, if an object has to accelerate from 0 mph how can it ever start to move at all, if at any moment no matter how slow it's moving, it was moving at half that speed previously? I guess the same aplies in reverse to any object coming to a rest as well.
Help, it's all too much.
