Phys 2.5 - The Pendulum 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: DanCreated on: 04-05-13 13:13 Give an example of oscillating motion A pendulum moving to and fro along the same line 1 of 13 Describe how a simple pendulum is made up? A simple pendulum consists of a mass called a bob, suspended on the end of a string 2 of 13 What happens when the bob is displaced to one side and then let go? The pendulum oscillates back and forth through the equilibrium position 3 of 13 Where is the equilibrium position found using a pendulum? Equilibrium is the position of the pendulum when it has stopped moving 4 of 13 Put 'amplitude of an oscillation' into simpler terms Time taken for one cycle, or time taken for the pendulum to swing one cycle 5 of 13 How do we work out the amplitude of oscillation? There are two ways, give me one Measure the time taken for the pendulum to swing from the highest position on one side to the highest position on the other side 6 of 13 Now state the second way of working out the time taken for one cycle Time taken between successive passes in the same direction through the equilibrium position 7 of 13 How do we measure the time period of a pendulum? We could measure the time for 20 oscillations and then divide the timing by 20 8 of 13 What does the time length depend on? ( How can we make the pendulum swing for longer) Increase the length of the pendulum 9 of 13 How do we find the frequency of oscillations? The number of complete oscillation per second 10 of 13 How can we work out the time or frequency of a pendulum? T = 1 / f 11 of 13 What is the time period of a pendulum of frequency 10Hz? 0.1 seconds 12 of 13 What does the time period of a simple pendulum depend on? The length of the string 13 of 13
