Science Simulations
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
About this simulation, When you press the button, you can see the corresponding strata. Combining the layer, you can create a variety of stratum. This simulation is presented as a mathematical model. Actual strata may be different.
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 force required to move the lever. Work at … more
‘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 direction. In the following cases, It is said … more
It is only the sun that shines by itself in the solar system. Earth and moon do not emit light themselves. The earth and the moon only reflect the light of the sun. Since the earth and the moon have … more
Assuming that the current flowing in the wire is in the X-direction, the magnetic field is in the Y direction. Then, what direction is the electromagnetic force? ‘Homopolar motor’ refers to a motor operated by using only one polarity of … more
This simulation assumes that the loading dye is 50bp and the marker is 50bp. (‘bp’ is a unit showing the number of base pairs of DNA.) Electrophoresis Electrophoresis is a chemical phenomenon in which an electric charge in a solution … more
Coriolis effect The French mathematician Coriolis first explained that the direction of fluid movement on the Earth’s surface is slightly warped. You can observe this effect in all spinning places like Earth. The Coriolis effect causes the following: 1. In … more
The sensing part is slightly different depending on the frequency of sound. Move the slide bar to check. Cochlear Inside our ears, there is a sensory organ that senses sound. The overall shape resembles a snail called ‘cochlear.’ The cochlea … more
You can drag the screen to rotate it. Temperate cyclone (also known as Extra-tropical cyclone) The temperate zone is where the north’s cold air mass meets the south’s warm air mass. When two different chunks of air meet, they cannot … more
