For T-shaped literacy, we had to watch a video explaining the difference between potential and kinetic energy. It included rollercoaster models, bow and arrows, pogo sticks, and microphones. I enjoyed getting to watch the video because it taught me a lot. I found it challenging to describe the variables for kinetic energy. To be BTB (Better Than Before) I could go into more detail for the first question- What is the difference between potential and kinetic energy?
What is the difference between kinetic and potential energy?
Potential energy is energy that will potentially be used, and kinetic energy is energy of motion.
What variable(s) determine the amount of kinetic energy?
The more potential energy there is, the more kinetic energy there will be. The faster an object is moving, the more kinetic energy there will be.
What variable(s) determine the amount of potential energy?
The higher the object is, the more potential energy it gains because it has further to go down. If you were to drop an egg from one meter it would break because it had a lot of potential energy that was turned into kinetic energy. But if you dropped an egg from 3 meters it would be absolutely pulverised because there was more potential energy stored, meaning that when it fell it was faster because the potential energy was turned into kinetic energy.
Explain how energy is transformed in a spring
When the spring is pressed together it holds potential energy. When the ends are released the potential energy is transformed into kinetic energy, making the spring bounce.
