Find a smooth, hard surface in your house or outside (no carpet). Make a mark on the ground. Get a ball or marble, and predict how far it will roll if you gently push it from your mark. Gently push the ball or marble, making sure that it does not hit a wall or a piece of furniture. Measure the distance it rolls, beginning at the starting mark you made. How close was your prediction? Why did the ball stop? What happened to the kinetic energy in the rolling ball? Give as much detail as you can.

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
