This lesson makes use of playground equipment including swings, a merry-go-round, slide, and seesaw to understand some basic principles of physics such Newton’s Law of Motion (especially 1st and 2nd), center of gravity, momentum, rotational inertia, torque, and …
Feb 18, 2011 · More like making a hamster run in a wheel to power a little light bulb, Ling’s Energy Harvesting Playground uses a prototype of an interactive see-saw powered by the kinetic energy of the see-saw’s up-and-down motion.
May 1, 2017 · A method is proposed for harnessing of human power based on children's play in playground and public places, on devices such as the seesaw, merry-go-round and swing.
Dec 8, 2016 · The turning effect of a force used in a seesaw is called the moment of force (see Diagram 2). You can find this by multiplying the force by its distance from the pivot point.
May 22, 2020 · The study aimed to design a low-cost prototype energy contraption using playground seesaw using locally available and recycled materials, to measure the voltage, current and power outputs produced at different situations and estimate the cost of the prototype.
Two children play on a seesaw and try to balance it such that the beam is horizontal and both of them are stationary. Assuming that both children weigh the same, they would have to be at an equal distance from the central pivot point to achieve this situation.
These problems highlight the opportunity to improve the seesaw energy harvester, particularly by exploring alternative mechanisms to harvest energy from a seesaw. This study proposes an alternative harvesting mechanism based on the electromagnetic regenerative damper.
Seeing those three forces, we may immediately think about net forces and begin to look for some overall acceleration of this toy and its riders. But we know that the seesaw remains where it is in the playground and isn’t likely to head off for Kalamazoo or the center of the earth anytime soon.
Jun 20, 2024 · One noteworthy instance is a playground in the Netherlands known for its sustainable energy approach. The designers incorporated swings and seesaws and a full suite of kinetic energy-generating equipment, resulting in significant energy savings.
While moving up and down, we think that our seesaw could produce a sustainable energy source to help reduce electricity needs in parks. We hope that this prototype can play a role in the real world or lay the foundation for the next generation of energy innovation.
