# Work & Energy Simulation

## Transmitting Electricity at High Voltages

Description of the simulation You can compare the two cases with each other. The power plant produced is assumed to be $$22,000V \times 1A = 22,000W$$. You can change the…

## 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…

Newton’s cradle Newton’s cradle consists of five iron balls, and each hung on two threads to prevent the ball from spinning. Originally Newton’s cradle was created to demonstrate Newton’s third law. If…

## 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…

## 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.…

## Conservation of Mechanical Energy

Potential energy The potential energy of an object is the energy stored in an object or system. Denoted as Ep. Generally speaking, potential energy refers to potential energy caused by gravity and…

## Potential energy due to gravity

Potential energy due to gravity Lifting heavy objects increases the potential energy of the object. The amount of work done when lifting an object of mass m by height h can be…

## Minimal force required for the lever

Lever A lever is a tool that transmits force using a rod. With a lever, you can work with it having little force. The length of the lever can adjust the minimum…

## ‘Work’ in science

‘Work’ in science ‘Work’ in science and ‘work’ in everyday life is a little different. In science, ‘work’ is to apply a force to an object and move it in the force’s…

## In a potential energy measurement experiment, why should an object be lifted slowly at a constant velocity?

In a potential energy measurement experiment, why should an object be lifted slowly at a constant velocity? When we apply a force to an object and move it in the direction of…
