Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due to a force‚ of an object have different accelerations (∆v/∆t). The more massive the object is‚ the smaller its acceleration. Newton’s third law of force says that if two object interact‚ the force F12 exerted by object 1 on object 2 is equal and opposite to the force F21 exerted by object 2 on object 1. The action force‚ F12‚ and the reaction force‚ F21‚ act on different objects. Illustration

DP Physics IA Thermal physics: Specific Heat Capacity of Metals Introduction: In this experiment we are going to measure the specific heat capacity of a unknown metal. To measure the specific heat capacity we will heat up the metal to certain temperature and release the metal in beaker filled with water. By knowing the mass and temperature of water filled in beaker‚ we will be able to calculate the specific capacity of unknown metal by change in temperature of beaker willed

pleiotropy is the single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Mutation in this type of gene will simultaneously affect more than one trait. An example is phenylketonuria‚ a human disease caused by mutation(s) in a single gene that codes for the enzyme‚ phenylalanine hydroxylase. The disease is characterized by mental retardation and reduced hair and skin pigmentation. List and explain other factors that

Taha Al-Yousif Hooke’s Law Lab Date conducted: September 18th 2013 Partners: Mohammed‚ Liam‚ Ben Nguyen Purpose: The purpose of this experiment is to find the relationship between the stretch of the spring and the attached mass and to verify that this relationship is accurately described by Hook’s Law. Theory: Hooke’s Law states that to extend a spring by an amount (Stretch) from its previous position‚ one needs to add an external force (Mass). Therefore

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

Purpose: To practice direct and indirect measurement Introduction: Do you think you could measure the average thickness of a sample of M&Ms without directly measuring selected M&Ms? The answer is "yes‚" and in this activity you will make direct and indirect measurements of the thickness of M&Ms. You will compare the results and evaluate the reliability of each method of measurement. Be sure to view the tutorial on the proper use of the vernier caliper. Please re-visit the information on when

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Motion of the Cars In this part of the experiment‚ we are trying to figure out how fast each of the cars are moving using our own measurements. We are also asked to make a mathematical equation that describes the motion. What we plan to do is use 2 meter long meter stick to measure the distance of the cars and record the position at each time interval. After that an average velocity can be found. After we used the average velocity‚ we were able to put it into the equation of a line formula and

Torque and Equilibrium Purpose: Apply principle of static equilibrium to determine a coefficient of friction. Research Question: What is the coefficient of friction between a meter stick and wall? Hypothesis: Tying a piece of string on to the end of a meter stick‚ put the other end of the meter stick against the wall so that the meter stick is horizontal and does not slide down the wall. Hang a weight on the meter stick sliding it to a point where the meter stick is about to come off from
