Oscillations
Oscillatory motion is motion that repeats itself. Oscillations are everywhere: guitar string,
pendulum, piston, neutron star (pulsar), drumhead, nuclear magnetic resonance (NMR),

Acceleration
Part I. Uniformly Accelerated Motion: Kinematics & Geometry
Acceleration is the rate of change of velocity with respect to time: a dv/dt. In this experiment, you
will study a very important class of motion called uniformly-accelerate

Force and Motion
In previous labs, you used a motion sensor to measure the position, velocity, and acceleration of
moving objects. You were not concerned about the mechanism that caused the object to move,
i.e. the forces that acted on the object
