Arithmetic Mean and Bounce Plate
Guessing the Bounce Plate Affect

Abstract

The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)), as that g is acceleration of gravity, h is the height of bounce plate, and H is the height of where the ball will be dropped. After completing this experiment the result was that the standard deviation was +/- 2.3 cmfrom the average value of 26.5cm. This was used for each variable H was 20cm and h was 20cm. Also there 18 trials performed as well.

Introduction

This experiment was to use kinetics of projectile motion and free falling bodies to determine the distance a ball will travel after it hits a bounce plate. To determine this we had to use the equations x=(1/2)at2 and v=v0+at and derive an equation that will determine the distance the ball will travel based on the height of the bounce plate and the height of where the ball will be dropped above the bounce plate. The equation made was g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)). From here we can make an estimate of how far the ball will travel after it hits the bounce plate.

Procedure

Materials needed:

• Steel Ball

Bouncing ball physics is an interesting subject of analysis, demonstrating several interesting dynamics principle related to acceleration. Almost everybody, at some point in their lives, has bounced a rubber ball against the wall or floor and observed its motion. Normally we don`t think about the details of bouncing balls physics too much as it`s fairly obvious what is happening, the ball basically rebounds off a surface at a speed proportional to how fast it is thrown. But what isn`t known to most is what is happening…

This experiment was completed using the already mounted projectile launcher (ME-6800). In this experiment, the program measures the flight times of two balls. The solid ball was placed in the free fall position and the hollow ball in the barrel of the projectile launcher. This was later reversed to test all possible flight times. The professor placed two time-of-flight pads at the two places where the balls would land. The launcher cord was pulled so the balls would be released. The…

To conduct our experiment, we used a meter stick on concrete and a tennis ball. We dropped the ball by intervals of ten from 40-100 centimeters above the concrete. To get the average ball-drop height, we dropped the ball three times from each height, found the mean. Our Y value represents the average bounce heights in centimeters and X represents the drop height in centimeters. We created a scatter plot to show our data (below).…

My data is good as I ensured that it was a fair test by keeping the type of ball, surface, pressure applied on the ball, balls mass and dropped repeated the experiment 3 times so therefore the data is reliable. For one of the bounce heights we got anomalous results however this could be due to human error. To improve my results I could have used a camera or transparent tube so we get accurate results as it’s hard to measure a balls bounce height with a naked eye.…

Graph 1 shows patterns observed with parachute shape. The patterns observed are that the octagon has much slower speed than all the other shapes. The rectangle shape parachute is the fastest speed. The R squared value looks at the points of data and their variations to determine a strong or weak correlation. The rectangle shows the weakest points of data and the octagon shows the strongest points of data. It is noted that no control run is conducted in this experiment. When trialing the octagon parachute, the results show very accurate data. It shows that it is the slowest speed, and experiences the most air resistance. The square parachute has the second most accurate data, based on the standard deviation from the mean. The speed of the square is the second slowest, and experiences great air resistance. The circle experiences fast rates placing it in third. The data is not as precise as the square and octagon. The rectangle experiences very fast rates, placing it in last place. It does not experience much air resistance, and the data is the least accurate. The rectangle had the largest average…

When we decrease the height of the ball release, with a subsequent increase of the ball velocity at the instance of release may lead to less accuracy if the jumping short distance in increased. It is advised that we slightly reduce the velocity to enhance accuracy. Accuracy can also be enhanced by reducing the height of release. To reduce velocity the following concepts of physics in the area of kinematics should be taken into consideration.…

Our purpose for this lab was to observe projectile motion and use the equations of motion to predict the objects location in different instances of time. We used a projectile launcher and a ball to observe these properties of motion. The main equation used in this lab was d=Vit+1/2at^2 where Vit will produce the distance due to constant motion and 1/2at^2 will produce distance traveled due to accelerated motion or gravity in this case.…
