Bowling ball and table! Can anyone please help me figure this one out; A bowling ball of mass 7.5kg traveling at 10m/s rolls off a horizontal table 1.0 m high. Calculate the velocity of the ball as it reaches the floor, ignoring air resistance and having an acceleration due to gravity of 9.8m/s.

The typical rubber sheet bowling ball analogy to "explain" gravity visually in layman's terms always seems to be two space dimensions. Why don't we use one dimension of space and the other of time? Both are curved by mass and everybody takes Eucledean/Cartesian type flat graphs of, say, x and t...

I need some help on a question: When a bowling ball rolls down a level alley, does Earth's gravity do any work on the ball? Explain with the use of a diagram. I need help b/c I don't know if the Earth's gravity will effect the ball since the alley is not tilted. Thanks.=)

I think this is a fairly basic question, but I have been out of physics since high school. Let's assume that I have two identical bowling balls, except that one is 15 lbs and the other is 16 lbs. If we avoid discussion about ball rotation and friction on the lane, how much additional speed...
