Conservation of Mechanical Energy

Mechanical Energy Conversion 2

Mechanical energy As the roller coaster descends from a high place, the height decreases, and the speed increases, so the potential energy decreases, and the kinetic energy increases. Therefore, potential energy is converted into kinetic energy … more

Where did the droplet's energy go? (The second law of thermodynamics and irreversible phenomena)

Where did the droplet’s energy go? (The second law of thermodynamics and irreversible phenomena)

* In this simulation, the attraction between particles is not considered. Where did the droplet’s energy go? Let’s think about the free fall of a water drop. From a macro perspective, falling water droplets change position … more

Where did the pendulum's energy go? (The second law of thermodynamics and irreversible phenomena)

Where did the pendulum’s energy go? (The second law of thermodynamics and irreversible phenomena)

Where did the pendulum’s energy go? A pendulum that vibrates in the air continues to collide with air molecules in the process of vibrating. Air molecules get their energy from the pendulum. In this process, Air … more
