Force Simulation
Buoyancy Experiment
The fluid in the beaker is water, and its density is assumed to be 1 g/mL. The volume of the object is assumed to be 100 mL. Buoyancy When we wear a life jacket, our bodies float on the water … more
Archimedes Buoyancy 1
Why is the submerged volume important to understand buoyancy? It is so famous that the 3rd-century Greek philosopher Archimedes shouted “Eureka!” and ran out of the bathhouse naked. (What did Archimedes find out? – Quotations from middle school science textbooks) … more
General Relativity of Gravity
* After setting the small object’s mass, position, initial velocity, and initial direction of movement, turn on the ‘Run’ checkbox to start the simulation. * The gravitational constant of the celestial body were assumed to be ‘1’. General relativity General … more
Earth’s gravity
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
Range and Intensity of the Gravity
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
Gravitational Lensing
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
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
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. When the length of the pendulum is \(l\), let’s consider the pendulum raised and … more
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 (mass, spring constant). The spring is very light, … more
Spring Scales
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 out the gravity (or … more
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 the magnitude of this force is the product … more
