Frictional Force – Let’s Investigate the Motion of Objects Under the Influence of Friction!
force vector rigid body conveyor belt Slow Reset Description : This page is for checking frictional forces and the motion of objects. Move your hand to stretch and compress the spring, applying elastic force to the object connected to the spring. The object experiences frictional force from the floor and initially stays at rest due to static friction. However, as the elastic force increases, the static friction force reaches its maximum limit (maximum friction), and the object starts to slide, transitioning to kinetic friction. By adjusting the static friction coefficient, kinetic friction coefficient, and the mass of the object using the sliders, you can observe how the motion changes under different conditions. Next, check the "force vector" checkbox to display the force vectors and observe the forces at work. When you check "rigid body," the object is treated as a rigid body with uniform density in the shape of a rectangular prism, and the position of the normal force's point of action changes. In reality, the point of action of the normal force does not move outside the object's bottom surface, and in such cases, the object will rotate and topple (in the graphics, instead of rotating, a message is displayed). Also, check the "conveyor belt" option to change the floor into a conveyor belt. Adjust the belt speed with the slider and change the friction coefficients and mass to see the object undergo various patterns of oscillatory motion. ● By moving the right end of the sliders for the static friction coefficient, kinetic friction coefficient, and mass at the bottom of the diagram, you can change these values. ● By checking the "force vector" box, you can display the force vectors. ● By checking the "rigid body" box, the position of the point of action of the normal force is calculated and displayed when the object is treated as a rigid body with uniform density in the shape of a rectangular prism. If the object rotates and topples, a message will be displayed. ● By checking the "conveyor belt" box, the floor will change into a conveyor belt. By moving the belt speed slider, you can change the speed of the belt. ● By checking the "Slow" box, you can slow down the motion for easier observation. ● The "Reset" button will return the object to its initial position at rest.
