Simple Harmonic Oscillators (SHO)


PURPOSE

Recognize and analyze periodic motion, along with what factors affect it. Next, we will study period, frequency, and amplitude (characteristics of motion). Finally, we will study a special motion called damped motion, or when friction affects the system drastically, and see how it relates to simple harmonic motion.



EQUIPMENT

• Force sensor (on a stand)• Motion sensor (on the floor)• Two springs (one long, one short)• You will attach the springs to the force sensor, and attach a mass at the end



PROCEDURE

Activity 1, 2 – Properties of Periodic Motion

• These first two activities are intended to check the following principles of periodic motion• Position• Velocity• Acceleration• Force

• Rely on the manual to figure out how these affect motion! Just be careful NOT to let the masses crash into the motion detectors!



PROCEDURE

Activity 3 – Simple Harmonic Motion• In this activity, you will check to see

how the following principles affect a SHO:• Amplitude• Spring Constant• Mass

• Your procedure will be essentially the same as that in Activity 1 and 2. Just follow the manual!



PROCEDURE

Activity 4 – Damped Periodic Motion• Remember that a damped motion is one

where friction has a great affect on the way the object moves.

• You will analyze distance-time, velocity-time, acceleration-time, and force-time graphs to see how damping changes your oscillations. You will also use acceleration-force and velocity- position graphs to compare to some of your results in Activity 1.
