Observe: Drag the ball to the 1-m shelf on the SIMULATION pane. What is the ball’s potential energy (PE)? Move the ball to the 2-m shelf. What is its potential energy now? What do you think the ball’s potential energy will be on the 3-m shelf? The 4-m shelf? PE on 3-m shelf: PE on 4-m shelf:

There are main groups in the modern periodic table of elements
