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. * As the operation is … more
Motion
Movement of an object suspended from a pulley
Movement on the pulley Two objects are connected by a string on a fixed, frictionless pulley and are moving together. In this case, the mass of the string and pulley is ignored. Since tension \(T\) and gravity \(g\) act in … 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 indicates the speed. A … 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 adjusting the drag speed. … more
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 absence of air resistance, the only force acting … more
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 change is doubled or tripled. If the force … more
