The factor I have chosen is the change of length of the graphite paper. To ensure that my test is accurate I will have to make it a 'fair' test. For example I will use the same piece of graphite paper throughout the experiment, as some of the graphite paper may be different in thickness and width. I will also use the same ammeter, power supply and converted bull dog clips because they may be slightly different and if they are changed the results will vary compared to other results obtained by different apparatus. For the experiment I plan to use suitable equipment for the particular variable.
Harmonic Motion: The Spring Objective: The purpose of this experiment to study the simple harmonic motion of an object placed on the spring. Harmonic motion involves the principle of oscillation where the spring force is proportional to the spring?s elongation. This means that the further the spring was stretched, there was increase in the force in order to keep the spring extended. The experiment is divided into two parts. In the first part, I measured static equilibrium and in the second part, I measured the period of oscillation known as dynamic oscillation.
Average Spring Constant and Uncertainty of the Batch Outline plan ============ I have been given 3 springs to which I will add different weight. Using the value of extension (Î”x) I will calculate the spring constant. Hooke's Law says that the stretch of a spring from its rest position is linearly proportional to the applied force (stress is proportional to strain). Symbolically, F = kÎ”x Where F stands for the applied force, x is the amount of stretch (found by new length minus original length), and k is a constant that depends on the "stiffness" of the spring, called the spring constant. [IMAGE] Trial plan ========== Set up equipment as above.
I will carry out a different exercise at each station for 30 seconds. Circuit training will improve my muscular endurance, cardiovascular endurance, aerobic fitness, muscular strength, and my speed and agility. It is important that each station works a different muscle group so that one group does not get over worked and cause damage. Circuit training is a training method which I feel will prove very good on improving my endurance and stamina. In the fitness tests I expect there will be a lot of difference when it comes to things like strength testing because of the gender related hormones produced by different sexes.
I will first exercise for 15 seconds then measure my pulse rate for 15 seconds then rest for 2 minutes then repeat the process. I will do this 3 times then increase the amount of time I exercise for to 30 seconds and do the same but exercise for 30 seconds. I will increase the amount of time I exercise for by 15 starting from 30 then, 45,60,75 and then 90 seconds. I will make sure results are reliable by repeating them if they are slightly unreliable. I predict that as the amount of time I exercise for increases so will my pulse rate.
Investigating Energy Stored in a Spring What is the spring constant? ============================ Planning Aim - to gain an average compression rate of the spring in the trolley in order to find the spring constant. Apparatus Clamp stand 2 clamps 2 bosses, 24 0.98N weights 2 weight holders 3 labels Pencil Sprit level Trolley Ruler (measures to nearest 5 x 10-4m) Diagram Plan - I am going to investigate the spring constant of the spring in the trolley to enable me to calculate the energy stored in the spring in the major investigation. To calculate the spring constant, I need to plot my results onto a graph and draw a line of best fit. The spring constant is equal to the gradient of this straight line.
Then finally I am going to do hard running for exactly one minute, and after that minute, I will measure and record my heart rate 3 times, also for one minute. The apparatus that I will use to carry out my experiment consists of: a stopwatch, a pen, a pencil, a ruler and paper. To get reliable and detailed results, when exercising and measuring the pulse of my heart rate for one minute, I will use a stopwatch/clock, by doing so, it increase the accuracy of the test. Furthermore, when I am regaining my resting heart rate for five
I think these are: Â¶ Length of wire Â¶ Diameter of wire Â¶ Material/type of wire Â¶ Temperature I am going to try and find out how the diameter of the wire affects the resistance of the wire. I will do some tests find out how the diameter affects the resistance. I think that if I increase the diameter the resistance will decrease. Method ====== 1. First I will set up a circuit with a power pack, voltmeter, ammeter and a space for a 1metre wire.
As for my start, when I do the run up, which is not often, but when I do I would hold my javelin at the head height with elbow bent 90˚ upwards. Though when I do t... ... middle of paper ... ...nd stick to it. I’ll achieve this goal before my next event. Technical What needs to be improved? • Approach run: I need to improve my techniques for approach run, therefore to improve this I need to repeatedly do specific drills that focuses on my run up and follow my training program.
Measuring the Viscosity of a Liquid Aim The aim of this experiment is to find out how fluid Bath Oils really are by measuring its viscosity. Plan The first thing that I'll do is to measure the spheres volume by first measuring its radius. I will then, by calculating the spheres mass, be able to calculate the density of the sphere. This will be used later when calculating the viscosity of the bath oil. I will then find the density of the bath oil, also used during calculations later on.
