A while ago, my friends (Shantha and Lauren) and I got the opportunity to swing on swings! We hadn't done that in a long time so we pretty excited and we got our other friend, Kelsey, to take pictures. haha yeah. So swinging on swings could be an example of many physics problems, especially energy, in the form of a pendulum. When we first sat on the swing, we had zero kinetic energy and zero potential energy. As we swung and "pumped" our legs to get higher, we gained both kinetic and potential but at different times in the pendulum. At the peaks of the motion, we would have a high potential energy but zero kinetic energy. As we accelerated towards the ground, our kinetic energy would increase as the potential energy decreased.

swinging was perhaps the best part of my childhood. but, i always got too scared to jump off when i got really high up.
OH!
is this last year at the FIESTA!?
haha
Hey! i remember that day! we had oodles of fun!
cool.
idk why but when i was a kid i could never swing without someone pushing me. i only could do it on my own until i was around eightish or so. yeah but i really do miss those days in preschool a lot. :)
senor frogs is so fun! so are swings. i get kind of scared though...
