Introduction

============

Newton discovered 3 laws of motion. They were:

· Newton’s first law of Motion was “Every object in a state of uniform

motion tends to remain in that state of motion unless an external

force is applied to it.”

· Newton’s second law of Motion was “The relationship between an

object's mass m, its acceleration a, and the applied force F is F = ma.

Acceleration and force are vectors (as indicated by their symbols

being displayed in slant bold font); in this law the direction of the

force vector is the same as the direction of the acceleration vector.”

· Newton’s third law was “For every action there is an equal and

opposite reaction.”

His first law we now know as the “Law of Inertia” and recognise

essentially as Galileo’s. It basically means if there where no gravity

or any force around, (like in space) if you threw a ball then it would

carry on going until something stopped it.

His second law is the most complicated out of the three. It is a

simple equation that can be used for almost anything to do with

motion. It sometimes also shown as F=mv. Where v is velocity as this

equation also works.

====================================================================

His third law is the shortest and easiest to get our head around. It

is simple yet very effective. Finally it is also most relevant to this

experiment.

- The Effect Length Has on a Pendulum's Period Prediction: I predict that the shorter the length of string, the shorter the time it takes for the pendulum to complete one period. The longer the length of the string, the longer the time it will take to complete one period. Equipment needed for experiment: -Clamp -Stopwatch -Bob/Ball -Metre ruler -String Obtaining the results: I will be measuring the length of the string in 10s, so that I can obtain a wider range of results....

## Investigating the Time Period of a Pendulum Essay

- Investigating the Time Period of a Pendulum The time period of a pendulum is the time taken for the pendulum to swing from one point to another point, for instance from point A to point B and back again. This diagram illustrates the experiment. This experiment calls for me to record this time period, however I feel it is too short, so I will time 20 time periods for accuracy. I will then take this number and divide it by 20 to give one accurate time period. When doing this experiment I will need to think of two independent variables: 1.... [tags: Papers]

## The relationship between the length and the period of motion of a pendulum

- Introduction: I chose to investigate this topic out of pure curiosity to see how the length of a pendulum affects its period of motion. A pendulum is a suspended point of mass, hung from a fixed point on an inextensible cord. When it is pulled and released from one side of its equilibrium, at x°, the pendulum swings back and forth on a vertical plane under the influence of gravity (La Né Powers, 2006). The motion is periodic and oscillatory; I am determining the oscillation or otherwise known as the period of motion (Resnick & Malliday, 1977, pp.... [tags: History, Galileo]

## The Simple Pendulum Experiment Essay

- The Simple Pendulum Experiment General Plan The first thing I am going to do is outline a general plan for this experiment. In this experiment, I am going to be measuring the effect of two variables on the time of one oscillation of a simple pendulum. The two variables that I have chosen are the length of the pendulum's string and the mass of the pendulum's bob. I will vary these two items and record results for the time of one oscillation of a pendulum with different mass/length of string.... [tags: Papers]

## Pendulum Investigation Essay

- Pendulum Investigation Plan Aim To investigate how the length of a simple pendulum will affect the time for a full swing. Variables Length The length of the pendulum has a large effect on the time for a complete swing. As the pendulum gets longer the time increases. As the pendulum gets shorter the time decreases. Air resistance A big and light pendulum bobble would be affected by a major amount of air resistance. This might cause the pendulum to move in a different way.... [tags: Papers]

## Effect Of Pendulum Essays

- The Problem Does the angle of a pendulum increase or decrease its swings per minute and what is the effect of the angle of release of the pendulum on it’s swings per minute. A pendulum is something hanging from a string or chain that when released, swings back and forth because of gravity ( “Academy Pendulums”). The swinging is caused by air resistance going in the opposite direction as the pendulum, making it go back and forth. A bob is the weight at the bottom of the pendulum. When a pendulum is released, it is pulled downward by gravity and accelerates 9.8 meters per second as it falls.... [tags: Pendulum, Angle, Galileo Galilei, Measurement]

## Simple Pendulum Essay

- Name: ISMAILA LUKMON CEG no: 08036768 Aim: Measuring a simple pendulum Introduction: A simple pendulum is defined as an object that has a small mass, also known as the pendulum bob, which is suspended from a wire or string of negligible mass. When displaced, a pendulum will oscillate around its equilibrium point due to momentum in balance with the restoring force of gravity. There are many examples of pendulums around us. A swing on which a child can ride. A plumb line used by builders to obtain a true vertical measurement.... [tags: Pendulum, Oscillation, Harmonic oscillator]

## Pendulum Conclusion Essay

- Research and Background A pendulum is an object hanging from a fixed point with a mass that swings back and forth under the influence of gravity. Sometimes this mass is called a bob, as it bobs up and down as it swings side to side. Pendulums are acted upon by three main forces: gravity, tension, and air resistance. While gravity always pulls down on the bob, tension pulls upward towards the pivot point for the string on the rod, or where the string pivots. However, both the amount and the direction of the pendulum’s tension changes as it swings.... [tags: Energy, Pendulum, Kinetic energy, Angle]

## Factors that Affect the Period of a Pendulum Essay example

- Factors that Affect the Period of a Pendulum Purpose: To determine the factor(s) that affect the period of a pendulum. Hypothesis: The factors that I think will affect the period of the pendulum are the displacement and the suspended mass because if the mass of the bob is a lot than it will take more force for the pendulum to swing and if there's a high displacement it will give the pendulum more energy to complete the cycle. Materials: stopwatch 100, 200, and a 500g bob protractor meter stick string Procedures: 1.... [tags: Papers]

§ Started with the string short

§ Used protractor to find 10°

§ Started stopwatch as we let go and recorded 1 period then stopped

it.

§ We repeated the last step 4 times

§ Then we made string longer by 8 cm and repeated last 3 steps.

We then thought it would be easier if we let the pendulum do 4 periods

and time the total tie overall then divide it by 4 so to get the

average. Also we found out that it didn’t actually matter the angle

because as long as the string is at a constant length then the periods

are all the same because if you think about it, When the angle is

shorter and the distance the pendulum is going slower and when the

pendulum is going further and bigger period it travels faster so it is

always the same time for one period.

§ So we then started again and got the 10° with the protractor

§ Then started the stopwatch

§ Counted 4 periods

§ Then stopped stopwatch.

§ Made string longer and repeated last 4 steps.

Conclusion

In conclusion to the experiment I think that the graph shows that the

length of the string is directly proportional to the time for one

period because you can see a straight line. Also I have hand drawn

the graph below.
