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

The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore‚ in order to make the prediction accurate‚ how the horizontal and vertical components of a ball’s position as it flies through the air should

Motion of the Cars In this part of the experiment‚ we are trying to figure out how fast each of the cars are moving using our own measurements. We are also asked to make a mathematical equation that describes the motion. What we plan to do is use 2 meter long meter stick to measure the distance of the cars and record the position at each time interval. After that an average velocity can be found. After we used the average velocity‚ we were able to put it into the equation of a line formula and

constant. If a ball is attached to the end of string and swung at a constant speed (i.e. only the direction of the velocity is changing not the magnitude) then there must still be an acceleration. The acceleration is directed towards the center of the motion. This acceleration is call centripetal acceleration! 2.6.2 State the expression for centripetal acceleration. The acceleration of any object moving in a circle at a constant speed is given by the equation: (1) a⃗ =v2r It is important to note

One Title: Determination of the acceleration due to gravity with a simple pendulum Introduction and Theory: A simple pendulum performs simple harmonic motion‚ i.e. its periodic motion is defined by an acceleration that is proportional to its displacement and directed towards the centre of motion. It can be shown that the period T of the swinging pendulum is proportional to the square root of the length l of the pendulum: T2= (4π2l)/g with T the period in seconds‚ l the length in meters

A circus is an arena for acrobatic exhibitions and animal shows. Usually circular and surrounded by tiers of seats for spectators‚ a circus may be in the open air but is usually housed in a permanent building or sheltered by a tent. The term circus is also applied to the performance itself and to the troupe of performers. The entertainment offered at a circus generally consists of displays of horsemanship; exhibitions by gymnasts‚ aerialists‚ wild-animal trainers‚ and performing
