Conical pendulum
3 forces acting on a conical pendulum Gravity(=mg): The force the Earth pulls. Tension: The force applied to both ends of the thread. Tension is always directed to the center from both ends. Centripetal force(Fc): The … more

This simulation ignored the effects of friction. Simple harmonic oscillation In everyday life, we see a lot of movements that repeated the same oscillation. Like below, shaky or suspended objects are doing this oscillation. Clock pendulum … more
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 … more
A pendulum that vibrates is one of a ‘simple pendulum’ or ‘physical pendulum.’ A simple pendulum is a case in which an object’s angular motion can be ignored, such as a small object suspended from a … more
Why do we always see the same side of the moon? The moon’s rate of rotation and rate of revolution is the same.

Like this simulation, if you drill a hole in the earth and throw it in, you can send it to the other side of the earth. This simulation ignores the effects of friction. The earth is … more
The reason why the moon rises 50 minutes late every day While the Earth rotates once a day, the Moon moves to the east little by little. So it takes 50 minutes to 24 hours for … more
