Oscillations of a Mass - Spring System Determination of “K” by the use of a Spring Oscillations System Experiment #3 for AMS320 involves a spring oscillating system to determine the value of “K”, the force value of an oscillating spring system. The spring is secured to a solid point and allowed to hang vertically below the solid stand. On the bottom of the spring is attached a steel ring with in which to attach a known amount of weight in (kg). The weights are added to the ring and the spring is pulled into a small amount of tension and released. The spring will then oscillate up and down and a stopwatch will be used to measure the amount of time it takes the weight and spring system to stretch and recoil ten times.
The purpose of this experiment was to measure centripetal acceleration and a centripetal force of a mass. The mass was then hung on an apparatus and attached to a spring. The mass was then rotated. The centripetal force was calculated using measurements of radius of the path, the time it takes to revolve around that path, and the mass. Procedure The group first took measurements such as the mass of the object, the radius of the rotation, the tension of the mass when we attached it to the apparatus.
Weighing scale * The clamp should be placed tightly on to the desk. * The Pole should be placed in one of the hole in the C-clamp * The right angled clamp should put on top of the pole * The spring screwed on to one of the jutting screws. * Tape the ruler to the pole as accurate as possible under the unextend spring. Lab set up Method: 1. Weigh each mass on a weighing scale and record on data table with uncertainty.
Period of a Pendulum Question: What factors will affect the period of pendulum? Hypothesis and Background: Pendulum - A weight suspended from a pivot so that it can swing freely. Equilibrium Position - When the weight is hanging straight down. Amplitude - The angle of the weight from the equilibrium. Period - The length of time it takes for a cycle of some repeating event (like the swinging of pendulum) to occur.
Description: In these series of experiments the apparatus we used was a spring gun that for the first experiment shot a steel ball freely which eventually struck the floor. For the second and third experiments the gun fired the steel ball into a pendulum. To measure the velocity of the steel ball, when it was launched freely, carbon paper and a 2-meter ruler were used to determine the distance it travelled and then kinematics were used to calculate the balls initial velocity. When the steel ball was launched into the pendulum the laws of conservation of energy and momentum were utilized to determine the balls initial velocity. Theory: 3 Kinematic Measurement of Speed In this experiment the steel ball was moving in two dimensions both horizontally and vertically.
Pendulum Aim: To investigate the time for 1 oscillation for different lengths of pendulum and different masses for the pendulum bobs Hypothesis: The time taken for oscillation is proportional to the lengths of the pendulums Apparatus: * A retort stand * Strings * Masses( big, medium and small balls) * Metre ruler * Stopwatch Procedure: 1. Fix the iron stand on the bench 2. Hang the mass on the end of strings and the iron stand 3. Measure the lengths of pendulum with the metre rule 4. Displace the masses to cause oscillation 5.
Physics 11 IB The Simple Pendulum Rajesh Swaminathan June 18, 2006 1 Aim To investigate the motion of a simple pendulum and to derive a value for g, the acceleration due to gravity. 2 Planning 2.1 Hypothesis By using other methods to determine the acceleration due to gravity g, the value of g should be close to 9.8 m/s2. 2.2 Procedure 1. Measure, record and average a reasonable number of measurements of the period T for 6 to 8 different lengths. 2.
Also a pulley with a table mount is required to support the string. As well two pieces of masking tape were needed in order to mark where point A and B are located. Finally a newton spring scale was required to measure the masses in newton. There are two separate procedures in this experiment that will test the relationship between the cart and the mass. The first part the lab is to determine the relationship between the cart and mass if the cart’s mass was left at a constant.
Apparatus: - A4 paper - Scissors - Meter tape - Chronometer - Scotch tape Variables: Dependent variables: - Height from which the cone id released - Independent variables: - Time taken by the cone to fall - Constant variables: - Weight of the cone - Area of the cone - Wind in the room Method Step 1: take out the A4 paper, scissors and scotch tape. Step 2: make a cone shape, put a little piece of scotch tape to keep the shape together Step 3: decide on 6 basic heights to measure (reasonably tall and far apart 0.8 → 3) Step 4: Put the meter rule against the wall and label the 6 heights you decided on the wall so that you don’t have to measure the height each time Step 5: drop the cone from each of the heights (2 times each preferably, to avoid large errors), remembering that the tip of the cone has to be on the line. While the cone is first released start the chronometer and as it hits the ground stop it. Step 6: write down each of the readings taken, clearly on a table Step 7: average out the two readings taken from each height and label them on a graph. Step 8: find the gradient to find the average velocity Step 9: you can also calculate the average velocity at each height, by finding the average of all the velocities the total average velocity can be measured with formulae velocity=distance/time, and therefore compared to the gradient
