Question

1. why does a pendulum lose height each swing, while a roller coaster with boosters can reach higher each time?

Explanation:

A pendulum loses height due to energy - dissipation from air resistance and friction at the pivot point, converting mechanical energy into heat. A roller coaster with boosters gains energy from the boosters, which add mechanical energy to the system, allowing it to reach higher heights.

Answer:

A pendulum loses height because of energy loss to non - conservative forces like air resistance and friction. A roller coaster with boosters can reach higher as boosters add energy to the system.
