Gravity my way...
When I saw the Grapple Project, http://scratch.mit.edu/projects/nXIII/876354
I saw that it simulated gravity. But it contains several other game elements that make it difficult to isolate the gravity simulation. So, I searched and found Scratch user nevit's simulation of gravity: http://scratch.mit.edu/projects/nevit/676476
I copied it an created a remix that helps me develop my understanding of Scratch and may help others see gravity in new ways. Changed the dropping object to a ball, added a constant x-component to its motion, and added a trace to visualize the motion. It reminds me of the strobe pictures that were part of my physics textbooks.
