in a simple harmonic motion system, the restoring force acting on the mass in the system is proportional to the?
Spring-bound block movement.
Simple dance movement. Swing-like motion.
This movement is described by the amplitude of the vibration (which is always positive), the periodic time (the time it takes for the body to make a complete vibration (vibration)), the frequency (the number of vibrations (vibrations) per second), and finally the phase that determines the starting location of the movement on the sine curve, and each of the frequency The periodic time is constant, and the vibration amplitude and phase are determined by the initial conditions of motion.
hee in a simple harmonic motion system, the restoring force acting on the mass in the system is proportional to the?
One of the best examples of simple harmonic motion is a mass attached to a spring.
In the case of no spring expansion, no force affects the installed mass, i.e. the system is balanced and stable. When the mass moves away from the position of stability or equilibrium, the spring will exert a force to return it again to its original position.
In general, any system that moves in simple harmonic motion contains two main features. First, when moving away from the center of equilibrium, a force is exerted to return the system back to the equilibrium position. The force exerted is directly proportional to the displacement made by the system, and the example we have dealt with (the spring-mounted mass) achieves The two features.
Returning again to the example, when the mass moves away from the equilibrium position, the spring exerts a restoring force until it returns it again to its previous position, and as the mass approaches the equilibrium position, the restoring force gradually decreases because it is proportional to the displacement, so at the equilibrium position x = 0, this force does not exist The mass, but the mass still retains some of the amount of movement from the previous movement, so it does not stop at the center of equilibrium, but exceeds it, and then the recovery force appears again and slows it down gradually until it loses its speed in the end and reaches the position of equilibrium in the end.
