Mechanics is a branch of physics that focuses on the relationship between energy and force and their balance, deformation, or movement with objects. Galileo's law of free-fall movement, and Newton's law of motion, laid the foundations of dynamics. Mechanics can be divided into classical mechanics and quantum mechanics, classical mechanics mainly study low-speed or static macro objects, to explore the movement of the material and the interaction between each other, as small as the point of mass, to the galaxy, the universe; quantum mechanics wider range of applications , Mainly to describe the microscopic things (molecules, atoms, subatomic particles) theory.
Grandiose Coffee Cup of Coriolis Force
Follow the instructions of our onsite instructor and sit tight in the coffee cups. Before the coffee cups begin to spin, first observe the linear rolling track of the ball on the ground. Then, when the coffee cups are spinning steadily, observe the rolling track of the ball again. Is there any difference? If yes, is the change real or unreal? Before the coffee cup begins to spin, the instructor will start the "Foucault Pendulum" hanging at the center. After the spinning begins, is there any change taking place on the undulating plane? If yes, is the change real or unreal? These changes are all due to the "Coriolis Force." Is the "Coriolis Force" a real force? After leaving the coffee cup, watch the quad screen outside the railing, and observe the differences between a "rotating coordinate system" and a "stationary coordinate system" from the ball's rolling tracks or the pendulum's undulating plane.
Power Feedback System
This exhibit is installed with a "power feedback system," which re-harvests the energy of braking and is provided by Delta Electronics. Power equipment in the past uses braking resistor to decrease energy and achieve the purpose of deceleration. However, this process not only waste energy but also causes heat. The new system of Delta Electronics transforms the motor into a generator during the braking process, and converts the braking energy into electricity, which is transmitted back to the electric system for reuse, achieving the results of conserving energy and benefiting the environment.
Faithful Newton's Cradle
Newton's Cradle looks rather simple, just five balls colliding with each other. However, it can be displayed in various ways to test one's understanding of "energy" and "momentum." Pull up a ball and let it collide with the rest. Does it knock one ball flying or all four of them? Why? Pull up two balls and let them collide with the rest. What will happen, then? You will really need to think about it if you pull up three or four balls! In addition, what will happen when you pull up two balls from both sides and let them collide? Will they bounce back? If they do, is it because the balls have "smashed into a wall," or is it because of energy exchange between the balls from the right and the ones from the left? How will you test to find out the answer? The five balls on the right are of identical but lighter mass, whereas the ones on the left are of non-identical mass. What results will you get if you repeat the process mentioned above in these systems?
Capricious Chaotic Pendulum
Turn the knob at the center to adjust the lower T-shaped arm into an upward, vertical position. When all the short arms are stationary, loosen the knob to let the arm start falling and rotating. Repeat this process for a few times. When repeating, try to make the initial condition as identical as possible and see if the following swinging will be identical. You can also start from a different angle and observe whether the subsequent movement will be the same when the initial condition maintains almost the same. Is there any slight difference between the initial condition of each experiment?
