Nicole Watkins Persuasive Speech Specific Purpose: To persuade my audience to petition against Maryland’s law to identify “Pit Bulls” as a dangerous breed of dog. Six months ago‚ almost to the day‚ my best friend and her new puppy were attacked. She was dog sitting her grandmother’s Mastiff‚ whom at the time had no previous violent history. She kept the Mastiff and her puppy in separate rooms in order to make sure there were no problems‚ but that wasn’t enough. One day‚ out of nowhere‚ the Mastiff

The Physics of Balls Bouncing off at Surfaces Leader: Mr. Edrian Pantas Contador‚ Love S. Members: Espiritu‚ Ian Timothy Ecube‚ Lynn Kristine Magangcong‚ Ahlya Oliman‚ Genie Rose Chapter 1 Introduction 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

restitution will be measured between a ball and the ground. Throughout this extended experimental investigation the theory of whether or not different changing different variables can change the rate in which a ball can fall at and the height in which it bounces at. The motion of a bouncing ball can be analyzed into the motion of before‚ during and after impact of the ball contacting the surface. This investigation will analyse and break down the motions of a ball being bounced‚ into seven dynamic stages

Bouncy Ball Experiment Aim: The aim of this experiment is to investigate the efficiency of a bouncing ball‚ and the factors which affect its efficiency. Prediction I predict that the higher I drop the ball from the higher it will rebound up‚ because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up

yards from the ball until it is in play. The ball is in play when it is kicked and moves forward‚ the kicker can’t touch the ball a second time until it has touched another player. No Hands‚ please I bet you knew that one. Most people who know nothing about soccer still know that you can’t use your hands unless you are the goalie. This rule applies to any part of the body from the tips of the fingers to the shoulder. However every ball that hits someone’s arm is not a hand ball. It depends

How high does a ball bounce? Aim: To see how high the bounce of a ball is. The changed variables are the height of where the ball is dropped from. The independent variables of this investigation. The (dependent) variable that will be measured in this investigation is the bounce height of the dropped ball. This shall be observed with one person dropping the ball from above while another person watches the for the highest point the ball reaches. Three variables that could be affected

Tossed Ball Project PURPOSE: The purpose for the students of the Energy of a Tossed Ball Lab involved learning how to measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall. HYPOTHESIS: 1. The ball has potential energy while momentarily at rest at the top of the path. 2. The ball contains
