## 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

## 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

## Moment of Inertia

This simulation assumes that there is rolling friction and no sliding friction. The cylinder and cube assumed the density of iron (7.874 g/cm³). Why does a rolling object go down slower than an object that slides down? In conclusion, the … 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

## 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 the force, we say that we have done … 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

## The principle of riding a swing

Kids have the know-how, but they can’t tell the principal. “How can you go so high?” Some principles are difficult to describe in words in the world, even if everyone knows. I think one of them is how to ride … more

## What is the fastest at the moment of hitting the ground? (Terminal Velocity)

Mechanical energy Mechanical energy is the sum of potential and kinetic energy. Mechanical energy = potential energy + kinetic energy Em = EP + EK Mechanical energy conservation Without friction, the sum of an object’s initial mechanical energy is equal … more
