Experimental project: spring oscillator experiment
First, the experimental content
Through the spring vibrator hanging on the horizontal support, the motion law and related parameters of the spring vibrator are observed and studied.
Second, the experimental purpose
1. Through experimental observation and measurement, we can master the relationship between the period and frequency of the spring oscillator and the mass and elastic coefficient.
2. Understand the damping of the spring vibrator and the vibration characteristics affected by external force.
3. Cultivate the ability of experimental data processing and analysis.
Third, the experimental steps
1. Construct the experimental device of spring oscillator.
2. Measure the natural length, mass and elastic coefficient of the spring vibrator.
3. By changing the mass and length of the vibrator, the period and frequency of the spring vibrator are measured.
4. Damping and external force are introduced to observe the vibration of the vibrator after damping and external force.
5. Record the experimental data and process and analyze the data.
Fourth, the experimental requirements
1. The experimental operation should be standardized and cautious to ensure the accuracy and reliability of the data.
2. Pay attention to safety during the experiment to avoid injury caused by excessive stress on the spring vibrator.
3. The experimental report should include the experimental purpose, device diagram, data processing and analysis results.
What are the physical experiment methods?
1. The experimental method is to use relevant instruments or equipment, collect relevant data through careful observation, scientifically process the data, and draw correct conclusions or answers.
2. Equivalence method refers to putting forward a simple scheme or idea in the face of a complicated problem, so that their effects are exactly the same, thus making the problem from difficult to easy and finding a solution.
3. Equivalent substitution method is a physical method, which is not only a method for scientists to study problems, but also a common method for high school students to learn physics.
4. Comparison is the premise of abstract generalization. By comparison, we can establish physical concepts and summarize physical laws. By comparison, it can be identified and measured.
