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 pendulum can determine this acceleration. The only variables

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- The Backswing Bring your club

.:First experiment:. .Problem: How will the length of a pendulum affect the amount of swings per minute? .Hypothesis: I believe that the length of the pendulum will affect the amount of swings per minute because when the string is shorter in length‚ there would be less friction between the string and the atmosphere‚ causing the string to go faster. .Materials: * String ( should be 70-90 cm long) * Metal washers * Stopwatch * Metric ruler * Stand * Extra washers (You will

Aim What is the effect of differing pendulum length on its period? Hypothesis If the length of the pendulum is decreased‚ the period will decrease. Variables Independent: The length of the pendulum (cm) Dependent: The period of the pendulum (s) Controlled: The weight of the swinging mass The angle for maximum displacement Materials: Pendulum (can be as simple as a mass tied to string attached to a piece of cardboard) Retort stand and clamp Stopwatch Ruler Protractor Masking tape

the time period of a pendulum Aim: To investigate the factors affecting the time period of a pendulum. Introduction: The time period of a pendulum is the time taken for the pendulum to swing from the first position‚ A‚ through positions B and C and back to position A again. [pic] Many factors can affect the time period of the pendulum. These factors are: length of string‚ angle from which the pendulum is dropped‚ the air resistance and the weight of the pendulum. In this experiment I

Introduction: Aim: To find the relationship between the length of a simple pendulum and the period of oscillation. Research question: How does the string length of the pendulum affect the period of oscillation? Prediction: The longer the string‚ the longer it will take to make one complete oscillation. Variables: Independent variable: Length (L). Dependent variable: Period of oscillation (T). Controlled variable: Mass of the plasticine. Tools & Materials: Stopwatch. Ruler. String. Plasticine

Swing kids The Swing Kids (German: Swingjugend) were a group of jazz and swing lovers in Germany in the 1930s‚ mainly in Hamburg (St. Pauli) and Berlin. They were composed of 14- to 18-year-old boys and girls in high school‚ most of them middle- or upper-class students‚ but some apprentice workers as well. They sought the British and American way of life‚ defining themselves in swing music and opposing the National-Socialist ideology‚ especially the Hitlerjugend. The name "SwingKids"

Pit and the Pendulum Reader Response Poe’s story is of a person sentenced to death by torture during the Spanish Inquisition. The story is an account of the narrator’s time from sentencing and throughout his journey during incarceration. It’s a tale of hope and despair. A story of one’s mental ability while facing an eminent death. Of this the narrator says‚ ‘It was hope—the hope that triumphs on the rack—that whispers to the death-condemned even in the dungeons of the Inquisition.’ Unusual for
