1. Observe and nd a pattern In the following experiments, we will study the ability of objects to smash a piece of chalk. As you go through each experiment, think about what might increase the chalk smashing ability of the objects. a) Consider a l-kg block with a string attached to the top and Earth as your system. There is a piece of chalk sitting below the block. {Vilill the block have the chalk smashing ability or falling ability without the Earth in the system?) Li: You pull up on the string so that the l-kg block slowly rises about 0.5 m above the - i piece of chalk. After this lifting process, you release the block. chalk I: It falls and breaks the chalk
