## Force to move the pendulum

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.길이 $$l$$인 진자를 Let’s consider…

## Connection of springs

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…

## Spring Scales

The 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…

## Force on Inclined Plane

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…

## Little Prince’s Trampoline

All the forces of the universe act as ‘pairs’. How can a squid move that without fins? People may think of rockets through squid. Squid moves by squirting water out of the…

Three elements of power When a force is applied to an object, the movement of the object depends on the ‘magnitude’ of the force, the ‘direction’ of the force, and the ‘point…

## Gravity difference on several planet (with the scale that used on Earth)

Let’s measure my weight on several planets with the scale that we used on Earth. Newton explaining the gravity mathematically Every object has a gravitational field around it and attracts surrounding objects.…

## Range and Intensity of the Gravity

Gravity Every mass object has a pulling force. This force is proportional to the mass of the two objects, and inversely proportional to the square of the distance between the two objects.…
