Science Simulations
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 adjusting the drag speed. … more
Try pushing an imaginary ball placed on the table with your finger. If your PC doesn’t have a camera, it won’t work. When the web browser asks for access to the camera, please allow it. (Personal data never stored on … more
* Please refer to the text below for how to make a graph. Free fall motion If you hold the ball in your hand and release it, it will fall. In the absence of air resistance, the only force acting … more
Record of movements The motion of an object can be more easily understood by graphing it. In the time-distance graph, the slope is equal to the velocity. The average velocity that an object has moved over a certain period of … more
You can click various shapes on the left and right sides of the screen. What are the characteristics of a shape with a large moment of inertia? What are the characteristics of a shape with a small moment of inertia? … more
Gravity Gravity is the force that is attracted between all objects with mass. According to Newton, an object with mass attracts each other with force proportional to the two objects’ mass and inversely proportional to the square of the distance … more

Ticker Timer It is a device to record an object’s movement by taking a spot on a paper tape at regular time intervals. A typical ticker timer is plugged into a household outlet. So the ticker cycle of the ticker … more
Space-time warpage Einstein, famous for the theory of relativity, thought that the mass of an object warps space-time. The larger the mass, the greater the degree of time-space warp. He explained that an object’s falling or planet’s revolution is a … more
Force changes the motion Consider the process of changing the movement by applying force to the cart. If the amount of force acting on the cart is doubled or tripled, the speed change is doubled or tripled. If the force … more
Projectile Motion When you throw an object, the object falls with a certain curve. The object performs a parabolic motion. This is a motion on a two-dimensional plane, not a straight line. To understand this movement, it is necessary to … more
