Science Simulations
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, … more
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
Tension by gravity In physics, tension is the force on a string connecting two objects. Generally, the tension is calculated from both ends toward the center. When the length of the pendulum is \(l\), let’s consider … more
● It’s a tube. The radius of the tube is outside: inside = 0.75: 1. There is no rolling friction. ● It’s a tube. The radius of the tube is outside: inside = 0.5: 1. There … more
You can hang multiple springs by touching (or clicking) the screen. What’s the difference when connecting multiple springs in series or parallel? (Notice) All springs and weights each have the same properties (mass, spring constant). The … more
A spring scale is a tool that measures the mass and gravity of an object using the spring’s elastic force. The spring of this scale is lengthened by gravity and shortened by elasticity. You can find … 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
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
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
Gravity acts on all objects. Suppose an object is placed on an inclined plane. This object is subjected to a force that slips downward by gravity. If the slope is θ, then the magnitude of this … more
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
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 in velocity. If so, … more
