🎈 Imagine a swinging pendulum on a grandfather clock. As the pendulum swings left and right, its energy keeps changing between being at rest (stored energy) and in motion (moving energy).
At the extremes (furthest points of the swing):
At the centre (middle point of the swing):
🚗 Imagine a car on a springy track: When pushed and released, the car zips to the center of the track super-fast (lots of motion energy). But at the track's ends, it stops for a brief moment (all stored energy) before racing back again!
Did You Know? During one full swing (or cycle) of the pendulum
🎡 Imagine a Ferris wheel: If you're on a cabin, every time you're at the top (or bottom), that's like the pendulum reaching an extreme. The number of times you feel the "slowest" on the Ferris wheel (top and bottom) is double the number of full rounds you make!
Then, it takes 0.4s for half a swing. So, a full swing back and forth (complete oscillation) is 0.8s!
