TA’s name: I. Objectives - Measure the motion of a Simple Pendulum using a motion detector and record position v/s time by computer. - Investigate how the period varies with the amplitude. - Analyze the motion to determine damping constant and quality factor. II. Data

Undamped oscillations – tennis ball

Slope of T2 vs. L plot = 4.923 +/- 0.2372 s2/m

Make a bar graph in GA to observe the relationship between period and amplitude.

Damped oscillations – Styrofoam ball III. Data Analysis

Period of oscillations as a function of the pendulum length

- Based on the slope of T2 vs. L plot the experimental gravitational acceleration was calculated as follows: The slope of the graph is calculated to be 4.923.

Now, we know that,

Slope = 42/g

Therefore,

...

Introduction

Wrestling is a combat sport in which two opponents with the help of different grappling techniques like throws and takedowns, clinch fighting, pins, and joint locks try to obtain and maintain a superior position (Encyclopedia Britannica, 2014). Wrestling is a form of ancient martial art that was very popular in the Olympic Games in ancient Greece. It is believed that the ancient Greeks developed wrestling in order to prepare soldiers in hand-to-hand combat. After the Greeks were defeated by the Romans, wrestling was borrowed by the Romans who modified the sport by eliminating much of the brutality of the Greek way wrestling. ...

Physical Science Review

29. The Difference between Velocity and Acceleration Velocity is the speed rate that is measured in one instant, while acceleration is the measurement of speed change. For example, a truck if a truck is traveling 20 kilometers per one hour, then its velocity is 20km/hr but of the truck driver puts their foot down and the truck starts to speed up, the truck experiences acceleration. 34. Rabbit’s Average Speed

The speed is the distance/time so, since there is a given distance and a time, then

speed = 30m/2s = 30/2 m/s = 15m/s. 36. Hamster’s Acceleration 0 m/s 0 seconds 5 m/s 1 second 10 m/s 2 seconds 40. Net force ...
