Imagine you're in a physics class, and the teacher demonstrates an experiment with a pendulum. Suddenly, Drew's eyes catch the pendulum swinging with high energy. What do you think happened in the experiment to create that energetic movement Drew observed? 

• The pendulum's string must have snapped in two, releasing energy.

• A single pendulum must have swung quickly to accumulate that high energy.

• One pendulum must have moved slowly, gathering energy gradually.

• A duo or more pendulums must have interacted in harmony to amplify the energy.

Imagine Eric's desk as a complex energy grid, all components working harmoniously as he delves into his project. Suddenly, a surge from the power strip disrupts this balanced ecosystem, causing several devices to shut down! What mysterious force caused this electronic disturbance when the power surged?

• The sudden influx of electrical energy acted like a tidal wave, overwhelming the devices' circuits.

• The power strip, acting as a conduit, channeled too much energy at once, overloading the devices.

• The humming of the overloaded circuits sent vibrations through the desk, but did it really turn off the devices?

• As the devices overheated, they automatically powered down, but was that enough to cause a shutdown?
