Theory: The relationship between two physical quantities can be determined by graphical means. For a simple pendulum, the relationship between periodic time and length is given by the equation
Where, T is the periodic time, 1 is the length of the pendulum string and g is acceleration due to gravity A graph of periodic time against length should be of the shape shown.
Hypothesis: That the shorter you create the pendulum string, the shorter the time difference for a swing.
Method:
1.Attach the pendulum bob to the string and suspend from the clamp stand so that the string is 100cm in length. 2.Set the pendulum swinging by displacing the bob through a small angle. 3.Time 20 swings of the pendulum. Record the data.
4.Repeat step 3 twice more recording the data each time.
5.Repeat steps 1 4 for different string lengths.
Analysis:
The shape of Graph 1 suggests that the relationship between time and length is: T√1
This relationship is confirmed in Graph 2, where by finding the square root of the length creates a straightline graph for which we can confirm the mathematical equation in the theory section.
The gradient of the...
...Symbolic Rescue
On the surface, Edgar Allan Poe’s “The Pit and the Pendulum” relates the story of a man tortured by the Spanish Inquisition. The unknown narrator loses all consciousness when he finds out that he is to be sentenced to death. When he awakes to darkness confusion overwhelms him for he does not know what is to happen to him. After passing out several more times he starts searching his prison cell in the darkness and soon discovers that there is a deep circular pit...
...EXPERIMENT 2 Measurement of g: Use of a simple pendulum
OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum.
Textbook reference: pp1015
INTRODUCTION:
Many things in nature wiggle in a periodic fashion. That is, they vibrate. One such example is a simple pendulum. If we suspend a mass at the end of a piece of string, we have a simple pendulum. Here, the to and fro motion represents a periodic motion used...
...Physics Investigation: What factors affect the period of a pendulum?
By Tanya Waqanika
In this investigation, I will be looking at which factors affect the period (The time for one complete cycle, a left swing and a right swing) of a pendulum (a weight that dangles from a pivot so that it can swing freely). I will do this by tying a metal bob to a length of spring and dropping it from a certain height and measuring...
...Is gravity always 9.8m/s2??
INTRODUCTION: A simple pendulum consists of a mass m swinging back and forth along a circular arc at the end of a string of negligible mass. A pendulum is a weight suspended from a pivot so that it can swing freely. Gravity is the pull that two bodies of mass exert on one another. There are several simple experiments that will allow you to calculate the acceleration due to gravity of a falling object. A simple...

The Ballistic Pendulum 
Determining the initial speed of a projectile 




THE BALLISTIC PENDULUM
ABSTRACT
The experiment was carried out to determine the initial speed of a projectile:
i) by means of a ballistic pendulum.
ii) by measurements of the range and vertical distance of fall during its flight.
The initial speed for the ballistic pendulum was found to be 5.0551±0.0008m/s and the initial...

...How to Swing a Golf
Club
Step 1 Addressing the Ball
Approach the ball calm and comfortably.
Body over the ball, relax your arms and grip the club.
Step 2 Beginning the Swing
Start the club head back from the ball 3 feet.
Your body should stay in an aligned position, wrists and arms firm,
and a slight bend of your knees.
Move the club to waist high, keeping your lead arm straight, your
hips with a slight rotation away from the ball.
Step 3...
