No seriously though, I need help with the following questions for a test. If you guys and gals could help me out here, I'd be forever grateful. Oh yeah and the best answerer gets the prize points.
Please and Thank You! ^_^
1) Which has more inertia, a heavy ball or a light ball rolling at the same speed in the same direction? Which is more resistant to a change in motion?
2) What would happen to a baseball if you could throw it in outer space? (Please explain in terms of inertia and friction.)
3) A car travels along a straight road at a steady 40 mph. Are the forces on the car balanced or unbalanced? Explain?
4) Can a light object that was hit with a small force accelerate as rapidly as a heavier object hit with a big force? Why or why not.
5) If you hold a backpack in your hand, the force of gravity pulls it downward. What force keeps it from falling to the ground?
