in all directions. The knee joint is a compound condylar synovial joint and allows for flexion and extension of the leg. In this experiment the angle‚ angular velocity‚ and the angular acceleration of the knee and hip were analyzed in oscillatory motion. In the first set of experiments‚ the independent oscillation of the hip and knee were isolated and observed. Then the oscillation of these joints was viewed in conjunction while a subject walked‚ speed walked‚ ran‚ and walked on their tip toes.The

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

Thiscontainer could be displaced vertically in order to change the water level. We would thenmake a tuning fork vibrate above the pipe and change the water level until the resonance wasat maximum intensity.Hypothesis: The
