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 … 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 … more
Three Body Problem
x y Vx Vy * The mass and gravitational constant of the celestial body were each assumed to be ‘1’. * You can edit the position and speed of each celestial body while not running. * … more
Free Fall Motion Analysis
Why do light and heavy objects fall at the same time? The change in speed due to gravity is the same for all objects because the force and inertia acting on an object are proportional to … 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 … 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 … more
Graph of Constant Velocity Motion
The distance covered by an object moving at a constant speed increases proportionally with time. If the distance is plotted against time on a graph, it will result in a straight line with a slope that … more
“Free falling” or “Thrown to the horizontal direction”
How to use the simulation Drag the ball with your mouse to free fall it in the air. Drag your mouse on the cliff to observe the parabolic motion. You can change the horizontal speed by … more
Twin Paradox
Twin Paradox Twin paradox started as a contradiction in ‘time delay’ in Special relativity. The Twin Paradox goes something like this: (Contents vary depending on the media.) One of the twins stays on Earth, and the … more
Kinetic Energy
Kinetic energy All moving objects have kinetic energy. The kinetic energy Ek of an object with a mass of ‘m’ and a velocity of ‘v’ can be calculated as follows. \[E_{ k }=\frac { 1 }{ … 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 … 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, … more
