Question

at the beginning of this lesson, you wrote some notes about why you think swings move. now reflect on your original explanation. in the question below, explain how your ideas about how swings move have changed now that you completed the lesson. you pick directions listen explain how a swing moves. explain how this explanation differs from the explanation you gave at the beginning of the lesson. you can start your answer with: • swings move because... • my explanation changed from...

Explanation:

A swing is a pendulum - like object. It moves due to the conversion between potential and kinetic energy. When pulled back, it has gravitational potential energy. As it is released, this potential energy is converted to kinetic energy as it moves downward and forward. At the lowest point, kinetic energy is maximum and potential energy is minimum. Then as it moves upward on the other side, kinetic energy is converted back to potential energy. Without additional forces like pushing, it will eventually stop due to air resistance and friction. Since no information about the initial explanation is given, we can't fully answer the second - part about how the explanation changed. But in general, one might have initially thought it moves just because of a push and not understood the energy conversion process.

Answer:

Swings move because when they are pulled back, they gain gravitational potential energy. When released, this potential energy is converted into kinetic energy as the swing moves downward and forward. At the lowest point of the swing's motion, kinetic energy is at its maximum and potential energy is at its minimum. As the swing moves upward on the other side, kinetic energy is converted back into potential energy. Without external forces such as additional pushes, the swing will eventually stop due to air resistance and friction. My explanation changed from (no initial explanation provided, so unable to fully answer this part).
