Student: (Be sure to look over all your notes and be sure to know the following things) 1. Define Temperature‚ thermal energy and heat. 2. A 1.00 x 10²g mass of tungsten at 100°C is placed in 2.00 x 10²g of water at 20.0°C. The mixture reaches equilibrium at 21.6°C. Calculate the specific heat of tungsten. Cw = 4180 J/kg°C C= 171 J/kgOC 3. A certain metal has a specific heat of 400 J / kg oC. It absorbs 8000 J of thermal energy which causes its temperature to raise 10oC. How much

Kinetic Friction Experiment #13 Joe Solution E01234567 Partner- Jane Answers PHY 221 Lab Instructor- Nathaniel Franklin Wednesday‚ 11 AM-1 PM Lecture Instructor – Dr. Jacobs Abstract The purpose of this experiment was to examine kinetic friction and what factors affect it. We pulled a wood block across a surface to determine whether the surface area of the block or the type of surface affects friction. The surface area did not appear to affect friction‚ since there was a small percent difference

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

Experimental Errors and Uncertainty No physical quantity can be measured with perfect certainty; there are always errors in any measurement. This means that if we measure some quantity and‚ then‚ repeat the measurement‚ we will almost certainly measure a different value the second time. How‚ then‚ can we know the “true” value of a physical quantity? The short answer is that we can’t. However‚ as we take greater care in our measurements and apply ever more refined experimental methods‚ we can reduce

Casual Uncertainty Experimental Psychology Abstract The purpose in this study was to see how casual uncertain people define their initial interactions. This study included 53 undergraduate students enrolled in experimental psychology at UTPB. Included in the study were 43 women and 9 men‚ age ranging from 19 – 56. They were rated by two scales‚ casual uncertainty scale (Weary and Edwards‚ 1994)‚ and the definition of initial interaction scale (Douglas‚ 1991). The results did not conclude

For Lab 1‚ my partner and I will be demonstrating the law in which connects the period of the pendulum‚ expressed as T‚ to the length of the string‚ expressed a L. The system the lab will be based on will include a pendulum with a weight of W suspended at a fixed point by the string with a variable length of L and an angle theta to be measured using a protractor. The variable T will be measured as the period of time needed for the weight of the pendulum to swing back and forth once. For part 1 of

PDP Physics Lab Report – 01 NAME: Wang Xueqian DATE: 2014/06/21 Introduction In this experiment‚ we will investigate the relationship between the linear speed of an object and magnitude of centripetal force acting on it. We will use a stopper moving in a circle to create an upward force on the hanging mass; at equilibrium‚ the upward force on the mass will exactly equal the centripetal force.

In the Tumble Buggy Lab‚ my partners and I used several different methods to calculate the velocity of a Tumble Buggy. The methods we used were a meter stick and a timer‚ a Spark Timer‚ a Photogate‚ and a Motion Sensor. Each method was different but overall‚ our velocities were very similar. Using the meter stick and timer‚ our velocity was 0.22 m/s. With the spark timer‚ our velocity was 0.26 m/s. Next‚ the velocity found with the Photogate was 0.325 m/s. Finally‚ when we used the motion sensor

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count
