Simple Harmonic Motion
Use a force sensor and motion sensor to determine the spring constant by measuring the spring extension due to each of three different masses suspended from the spring.
This experiment examines one example of simple harmonic motion. A mass that is suspended from a spring is pulled down, released, and allowed to oscillate. The following will be examined:
Determining the spring constant by measuring the spring extension for each of three different masses suspended from the spring.
The relationship between position and time, velocity and time, and acceleration and time for the moving mass.
The relationship between the period of oscillation T, the spring constant k, and the oscillating mass m.
Students explore simple harmonic motion by:
- Using a force sensor and meter stick to determine the spring constant of a spring.
- Using a motion sensor and force sensor to measure and record force versus time, position versus time, velocity versus time, and acceleration versus time data for a mass vertically oscillating.
- Comparing graphs of force versus time, position versus time, velocity versus time, and acceleration versus time to observe relationships between the four measurements.
- Analyzing a graph of position versus time to determine which parameters influence the motion of an oscillating object.
Sensors / Equipment Used:
The PASPORT Motion Sensor accurately measures position, velocity, and acceleration of a target. Can be used to track the motion of carts, balls, people and more.
Designed to measure both pulling and pushing forces. Uses range from collisions to tug-of-war.
Assorted masses ~ at least 3
