to show that the acceleration is proportional to the force causing the motion. Theory Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the total mass. a = net force/ total mass If an object is acted on by a net force ‚ it will experience an acceleration that is equal to the net force divided by the mass. Because the net force is a vector‚ the acceleration is also a vector‚

FRACTIONAL DISTILLATION October 29‚ 2012 CHEM 210 ME01 INTRODUCTION The process of separating the components of a mixture by distillation into relatively pure fractions is referred to as fractional distillation. Simple distillation‚ a process with similar goals‚ is noted for being a satisfactory attempt at separating two components in an ideal mixture‚ but not as accurate as fractional distillation. To explore these statements further‚ there needs to be an in depth look at the theory that

Free-Fall Lab Assignment Nishad Gothoskar Physics Online Experimental Design: In order to design an experiment to measure free-fall acceleration‚ the researcher must construct a wooden tower with height 10 meters along with a trap door system to release a tennis ball from rest position. In this case‚ the researcher must measure the time the ball takes to free-fall from rest position to the ground. Using this info and the formula: s=vit+ 12at2 s = 10 m vi = 0 m/s The researcher will

height. Today in physics a two dimensional lab was done to decide the distance of an ice cream cone shooter. To do this‚ the formula (d=Ví t + (1/2) at^2) has to be implemented. I decided to make my Y equal to one meter‚ so my calculations would be easy to get. I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know that time is also .452‚ and that the acceleration is zero. To get started I decided the

These measurements had many possible sources of error including air resistance and firing position. This lab increased understanding of projectile motion. Introduction Projectile motion occurs when an object in a two dimensional plane experiences motion only due to gravity. Kinematic equations can be used to describe the components of projectile motion. This allows us to analyze the motion. In this lab measurements will be taken to determine the initial velocity of objects experiencing projectile motion

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done
