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 periods for this experiment varied from 0.6s to 1.7s and the frequencies varied

that would help you find g using a pendulum. Design an experiment and test your design using Moon and Jupiter. Write your procedure in a paragraph that another student could use to verify your results. Show your data‚ graphs‚ and calculations that support your strategy. The time it takes a pendulum to complete one back-and-forth swing‚ called the pendulum’s period‚ depends only on the pendulum’s length and the value of gravity. In an experiment‚ an experimenter can easily manipulate a pendulum’s length

P hysics 2 06 Example P roblems Newton’ s Laws of Motion Problem 1 . A) What is the direction of the acceleration of an object that is slowing down while heading northward? Answer : The acceleration would be southward since the net force required to cause this acceleration would be southward. The change in velocity is directed southward. B) What is the acceleration of an object thrown straight up in the air‚ near the surface of the earth‚ at the very top of its flight? Answer : The acceleration is

Projectile Motion By Kaneisha Winch Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion. Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity‚ the vertical velocity will remain the same. This has no relation to the size or mass of the ball. Materials: • a baseball with a diameter of approx. 7.5 cm • a tape measurer • a surface

Case Problem 2: The Motion Picture Industry This case provides the student with the opportunity to use numerical measures to continue the analysis of the motion picture industry data first presented in Chapter 2. Developing and interpreting descriptive statistics such as the mean‚ median‚ standard deviation and range are emphasized. Five-number summaries and the identification of outliers are also of interest. Interpretations and insights can vary. We illustrate some below. Descriptive Statistics

III. Data Analysis For this analysis‚ it was used descriptive statistics of a data set with four variables in order to describe the performance of the motion picture industry. First‚ the study involved measures of Location which include: mean‚ median‚ mode. In addition‚ it was analyzed measures of variability of the data set which include: variance‚ range‚ and standard deviation. Moreover‚ the outliers movies were identified by calculating the z-score of each variable. Finally‚ it was measured the
