What?
Gravity… it's the law. See if a falling quarter can bend the law of gravity by shooting sideways.
Materials:
• two rulers
• two quarters
• the edge of a table
How?
1. Slide one quarter to the edge of the table.
2. Lay one ruler so it lines up diagonally
to the table edge, one end hanging over, the other end touching the first
quarter.
3. Put the second quarter on the end
of the ruler hanging over the table.
4. Put your finger on the first ruler, pressing it onto the table, then use the other ruler to give it a good whack, hitting it near the end that hangs over. Watch those quarters go!
Why?
The quarter sitting on the ruler falls straight down, while the other quarter goes flying sideways. Will they hit the floor at the same time? The law of gravity says they will. No matter how fast the quarter shoots sideways, it will hit the floor at the same time as the other one. Don't just sit there… Get To It!
