Webcam Movement Analysis (on the table)
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,…

Analysis of Free Fall Motion
* 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…

Average velocity and instantaneous velocity
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…

Ticker Timer (Movement on the slope)
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…

F = ma (Newton’s law of motion)
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…

Parabolic motion (Monkey and Hunter)
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.…

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…

“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…

Condition of Uniform Circular Motion
Even if the force works, the speed does not change? When an object moves linearly at a constant velocity, the force applied to the object is zero because there is no change…

Three Body Problem
* As the operation is repeated, the above simulation may expand the error due to the decimal operation’s limitation. * If your computer is outside of the limits that it can handle…
