Description
Technical field:
The utility model relates to a kind of multi-functional single pendulum experiment table easy to use, belongs to experiment with simple pendulum technical field.
Background technology:
Physics be one taking experiment as basic science.On classroom, teacher lectures physical knowledge in conjunction with experiment, and student understands by experiment and grasps knowledge, only has experiment and textbook content teaching to combine, the teaching efficiency that just can obtain.New class mark physics teaching material comprises series of experiments project, and homework has also comprised a large amount of family's experiments, examines the experimental implementation of also having added an examination of in many provinces and cities, and this limit, raw limit of will going to school makes experiment, and will do more and test.
Acceleration is a physical quantity in physics, is a vector, is mainly used in the middle of classical physics, generally represents with alphabetical a, and the unit in International System of Units is the every quadratic power of rice second (m/s^2).Acceleration is velocity variable about the ratio that this variation time used occurs, and describes the direction of speed and the speed of size variation, is quantity of state.
Acceleration is caused by power, becomes a very important physical quantity in classical mechanics because of Newton second law.The acceleration of certain reference frame in inertial reference system shows as inertial force in this reference frame.Acceleration is also directly or indirectly relevant to multiple effect, such as electromagnetic radiation.
In the research of acceleration, acceleration of gravity is more common, because acceleration is an abstract concept, need to measure concrete data it is studied.
When the measurement of acceleration of gravity, using single pendulum, single pendulum is to thoroughly do away with flexible and length is constant, the negligible line of quality hangs a particle with one, under Action of Gravity Field, in vertical plane, does periodic motion, just becomes single pendulum.When single pendulum vibrates under pivot angle is less than the condition of 5 ° (being commonly considered as being now less than 10 °), can be similar to and think simple harmonic motion.The Period Formula of simple harmonic motion: T=2 π √ (L/g). wherein L refers to pendulum length, and g is local gravitational acceleration.
Utilizing Measurement of Gravity Acceleration by Simple Pendulum is a basic Physical Experiment, and in measurement, some primers will have influence on the accuracy of experiment structure, the first, and the measurement of pendulum length, it measures the accuracy that whether accurately directly has influence on experimental data; The second, whether form circular cone pendulum; The 3rd, the size of pivot angle.So in the time carrying out experiment with simple pendulum, need to use the cycloid of different length to carry out reference experiment, thus need on rocker, be provided with the cycloid of different length, due to limited space, the mutual grazing of swing ball when many cycloids can cause testing, cause testing structure inaccurate, and rocker places and must be the level of state, otherwise affect the definite of pivot angle, but while generally placing rocker, be all its level whether of range estimation, neither one is weighed device, causes testing structure inaccurate, and practicality is not strong.
