## Free Fall Experiment 2

This simulation allows you to measure speed as a function of fall height. You can ​​measure the speed at two locations and change the ruler’s orientation. Free fall movement All objects on Earth are affected by gravity. If there were … more

## Free Fall Experiment

This simulation allows you to measure speed as a function of fall height. Free fall movement All objects on Earth are affected by gravity. If there were no friction with air, the speed of any object would increase by 9.8 … more

Newton’s cradle Newton’s cradle consists of five iron balls, each hanging on two threads to prevent the ball from spinning. Originally Newton’s cradle was created to demonstrate Newton’s third law. If you collide a ball from one side, the exact … more

## 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 while the roller coaster … more

## 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 voltage and resistance of the transmission line respectively. … more

## 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 over time. In this … more

## 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 molecules increase their speed. … more

## 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 is proportional to an object’s mass and height. … more

## 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 obtained as (Potential energy by gravity) Ep(J) = … more

## Conservation of Mechanical Energy in Rollercoaster

Conservation of Mechanical Energy If you look at the roller coasters, you can find something interesting. That’s right. There is no engine on the roller coaster. When we lift the roller coaster to the highest point, then the roller coaster … more
