determines the density of a regular and diet soft drink in relation with the density of water in which a pycnometer was used to get their densities. 1. Introduction Relative density‚ or specific gravity‚ is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in modern scientific usage. If a substance ’s relative density is less than one then it is less

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

Gravity is the force that keeps objects close to the earth Not only does gravity keep objects close to the earth it also keeps the solar system revolving the sun Gravity was discovered by Isaac Newton Acceleration of objects that is due to gravity on Earth is 9.8 m/s Also‚ according to Mr. Newton’s First Law‚ once the egg was moving‚ it didn’t want to stop. The container of water interrupted the egg’s fall‚ providing a safe place for the egg to stop moving so you could recover it unbroken

in Lesson 1 is acceleration. An often confused quantity‚ acceleration has a meaning much different than the meaning associated with it by sports announcers and other individuals. The definition of acceleration is: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. Sports announcers will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to

LAB WRITE- UP NAME: MANOUCHEKA FIDEL DATE: 9/19/14 TITLE: BACK AND FOURTH MOTION PURPOSE (Introduction): To qualitatively analyze the motion of objects that move back and forth. Then analyze and interpret back and forth motion in kinematics graphs. Use kinematic graphs to catalog objects that exhibit similar motion. PRELIMINARY QUESTIONS: Finding the average velocity Do any of the four objects listed above move in similar ways? If so

Objective: To study the relationships between position‚ velocity‚ and time‚ with acceleration held constant‚ of an object moving in one-dimensional motion with minimum friction. A motion sensor will be used to measure various aspects of vector quantities. Description: An Air Track is positioned along the edge of the table. It is a long straight metal beam with many small holes that are roughly each 2mm in diameter. It is positioned at an angle to allow the gliders to glide down the slope

ACCELERATION: Good afternoon everyone! Our group will discuss about acceleration. But before that‚ what is acceleration? Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. People will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration

Lab #1: Projectile Motion Purpose: To determine experimentally the initial and final velocities of an air powered projectile. Hypothesis: If the angle of the rocket is launched at 45 degrees than the distance and velocity will maximize. Materials: Rocket launching platform Rocket launcher Rocket body Air pump Safety goggles Rubber washer Nose cone 40‚ 45‚ 50‚ 55 and 60 angle wooden blocks Measuring wheel Procedure: 1. The rocket was assembled by the rocket launcher
