Application of Physics Technology in Wahana Kora Kora
Physics is one of the sciences that underlies the development of science and technology. The role of physics is so important for the development of science and technology. The branch of physics that studies motion is kinematics. an object is said to move if the object changes position. The amount of change in position is stated as a change of movement. Displacement that occurs every time is called speed. If the speed of the object changes, it is called acceleration. Position, displacement, velocity, and acceleration are physical quantities that are directly related to the kinematics branch. The application of natural science technology in daily life on Kinematics is one of them Kora – Kora. Wahana Kora Kora is no stranger to people’s lives because it is often encountered at Wahana Permaianan, as well as at the Night Market. Wahana Kora Kora is a vehicle that tests mentally when going to ride it.
The Working Principle of the Kora Kora Vehicle
The Kora Ayora Boat Boat is a Korean-style barge that moves backward and swings high and causes thrilling sensations. The principle of this vehicle is almost the same as riding a swing, it’s just that the Kora – Kora swing can reach an angle of drift more than Ninety degrees (90 degrees). At first the Kora – Kora was swung upwards aided by the rotation of the tire rubbing against the bottom of the boat. Tire speed is controlled electronically. Then the boat was released gliding down due to gravity. Kora Kora deviation height can be adjusted by adjusting the tire rotation. The boat’s up and down movements repeat for two to four minutes. For the Kora – Kora vehicle, the maximum deposit is limited to around an angle of 90 degrees. Even though Kora Kora did not cross a full circle, passengers seemed to experience a full circle. That was because Kora – Kora swung back and forth on the half-circle curved track. This swinging motion causes a sensation of feeling caused by low h or maximum height and high g or minimum height to passengers.
Kinematics Application in the Kora Kora Vehicle
The Kora Kora vehicle is one of the many vehicles that uses the concept of physics in its application to the principle of the Kora Kora vehicle movement is Swinging Pendulum. The theory underlying the Kora Kora vehicle is the Pendulum theory, the quantities involved are Mass, Gravitational Force, Simple Harmonic Motion, Angular Deviation, Period, Frequency, Amplitude, Dipping Force on the Mathematical pendulum swing, Potential Energy, Kinetic Energy. Caring Works is an object with mass (m) which is at the end of a rope or a hanging rod. Dependent masses are given an angle deviation of theta and released. As a result the object is swinging back and forth or oscillation under the influence of gravity.
Oscillation is the motion of a point and back to the starting point on the axis. And the time required for a complete oscillation is called a period (T). period (T) is determined by the equation: T = 2pi (L / g) 1/2.
T = oscillation period
L = the length of the hanger rope
g = gravity acceleration 9.8m / s2
when the boat is swinging at the highest position, its potential energy is maximal and its kinetic energy is zero. Meanwhile, when it moves down, its potential energy decreases and its kinetic energy increases as a result of changes in speed and altitude. When we ride the kora kora, we will definitely feel when we ride or swing behind the passenger will feel the weightlessness when he is at the end of his height. Weightlessness experienced by passengers is not caused due to reduced gravity. But the result is a force on the seat or on other external objects which drive the weight of the passenger. Force from this external object will neutralize the force of gravity or downward force.
Psychological Effects When Riding the Kora Kora Vehicle
At the end of the height of the boat, passengers will feel a different sensation from normal conditions and as if going to fall or crash from his chair. Then the psychological effects felt by Kora Kora passengers are caused by the height position and swing speed. This causes passengers seated at the end of the boat to feel as if their bodies are pulled down stronger than passengers who sit in the middle of the boat. The physiological effects that arise are caused by changes in acceleration experienced by the passenger body. Under normal conditions, our bodies experience an acceleration of 1 g. which is one time acceleration of gravity. When Kora – Kora slides down, our body accelerates more than 1g.
