When something spins it undergoes “rotational motion”. When something spins around a single point it is called “circular motion”. B. We measure how fast something spins not in m/s (different points on the object are spinning at different velocities) but by measuring the angle described in a given time period. C. Angles can be measured in radians (rad) 1. The radian is the ratio of the arc length (s) to the radius (r) of a circle (insert fig. 7-1 here)

The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction. Displacement is the moving of something from its place or position. Free fall acceleration is when there is no air resistance affecting an object. equation for reaction time: t= 2Δx g constant acceleration equation: Δx = v0 t+ 12 at 2 Velocity:

spring (spring with a higher spring constant k) is used in the experiment then the frequency and centripetal force will both increase. If the spring constant increases‚ the plumb bob will have to rotate at higher velocity to become perpendicular to the horizontal shaft. A higher velocity means a higher frequency since the plumb bob is moving faster and is completing each rotation in less time than before. The centripetal force will be higher because the spring requires more force to cover less distance

Old Dominion University PHYS 111N Experiment 10 Harmonic Motion Submitted by: Lab Partner: Lab Instructor: Introduction In this experiment we will investigate the simple harmonic motion of an object suspended by a spring that oscillates on a vertical plane and in a separate experiment was examine oscillations on a horizontal plane. In simple harmonic motion‚ the displacement from the equilibrium position is directly proportional to the force. The force generated is always directed toward
