INTRODUCTION

1.1 Background of the Experiment
Mass density describes how heavy an object is. Defined by the Greek letter ρ, read as rho, density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids, density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1.
The SI unit of density is kg/m3. However, its CGS units, g/cm3 or g/ mL, are the most commonly used ones in the laboratory. The conversion is given by
1 gcm3=1gmL=1000 kgm3 [1].
The density of a homogeneous liquid is also defined by the amount of mass per unit volume. Liquid is usually confined in a container, so its volume is relative to the volume of its container [2]. …show more content…

Compute for the volume of the alumina balls by subtracting the initial volume from the final volume of water in the graduated cylinder. B. Calculate for the density of the alumina balls by dividing the measured mass by the volume. C. Record and compare the resulting density of the alumina balls with the standard value at room temperature.

    The factors that affect the motion of a falling object Scientific Knowledge When an object falls, many forces are acted upon it: gravity, friction, air resistance and, if in the water, up thrust. When an object starts to fall, gravity over powers air resistance, however, as an object starts to reach terminal velocity (its maximum speed) the opposite forces start to even out until they are equal. Some people believe that if the forces are balanced then the object has stopped moving, meanwhile they….
