Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of

Analysis Torque is the ability of force to change the rotational motion of a particle. It is also called the moment of force. It is always specified with regard to the axis of rotation. On the experiment the axis of rotation serves as the model balance. This means that as much as torque is directly proportional with the force applied on a particle‚ it is also dependent on the perpendicular distance of the applied force to the axis of rotation. On the first activity we need to determine

HYPOTHESIS - 1923 Haldane & Oparin propose hypothesis that life originated as simple molecules followed by cells - conduct simple experiments that show that organic compounds can form cell-like structures 3. EXPERIMENTATION - 1953 Urey and Miller collaborate effectively to design an experiment/model to simulate conditions on early Earth and test the hypothesis that life molecules could originate on Earth 4. RESULTS - Urey and Miller results confirm that simple

atrocities against other women? The usual answer is to portray women guards as more like surrogate men (Sarah Helm). Dr. Herta Oberheuser was one of the most cruel‚ gruesome female doctors in Ravensbrück. Dr. Oberheuser ran many different types of experiments‚ but she had two certain ones she focused mainly on. She would test different types of injections on children‚ such as evipen and oil. After waiting until they either died‚ or still may be fully alive and aware she would continue working on them

In the Milgram experiment‚ a man picks random people to participate in an experiment. They believe that they are helping discover the roles of punishment on behavior. Although‚ this is not true. The participants themselves are the ones being analyzed. The experiment is to discover how far someone would obey an instruction of harming another person‚ despite personal conflict. The participant and an actor are places in a room and “get to choose” their roles of either teacher or learner‚ although the

Assignment: Do sports drinks really work? Question... How do sports drinks affect muscle reaction time? Hypothesis My hypothesis is if sport drinks are consumed‚ then the reaction rate will improve. Sport drinks provide individuals with the required amount of water‚ carbohydrates and electrolytes (sodium and potassium) which is lost in sweat while exercising. Maintaining adequate electrolyte levels will enable better cell function‚ which is needed for muscle endurance‚ among other bodily capabilities

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

Bouncy Ball Experiment Aim: The aim of this experiment is to investigate the efficiency of a bouncing ball‚ and the factors which affect its efficiency. Prediction I predict that the higher I drop the ball from the higher it will rebound up‚ because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up

Performance (page32) 1. In this experiment‚ what might be some extraneous variables affecting the students’ test performance? 2. What might educators do to try to prevent the effect of the “dumb jock” negative stereotype on college athletes? The experiment done by Jameson‚ Diehl‚ and Danso‚ attests that a negative stereotype‚ being referred to as a “dumb jock”‚ may have negative impacts on the test performance of athletes. There were two groups in their experiment. The experimental group was exposed

compensation for participating in this experiment. These participants were divided into six groups based on where they were sitting. Design The Stroop Test was used in order to test the effect of interference on reaction time. This was done by using three different types of slides‚ each with either 20 words or 20 colored boxes‚ and recording how many words participants could read the color of‚ rather than the word itself. The colors used in this experiment were red‚ green‚ blue‚ purple and brown
