Lesson 9: d-t & v-t Graphs Graphing the motion of objects gives us a way to interpret the motion that would otherwise be difficult. ● Graphs will also allow you to show a large amount of information in a compact way. Essentially you need to be able to sketch and interpret two main kinds of graphs in kinematics: 1. Displacement – Time Graphs ● Sometimes called d-t graphs‚ or position – time graphs. 2. Velocity – Time Graphs ● Sometimes called v-t graphs. Displacement - Time (d-t) Graphs

practicalphysics.org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In order to find the acceleration due to gravity‚ the equation must be rearranged to look like this‚ and give “g” as

The system’s task is to assist the driver in demanding driving situations‚ e.g. if a wild animal suddenly runs across path of vehicle‚ and also to compensate for overreaction on the part of the driver and to prevent loss of vehicle stability. However‚ ESP is not intended for speed manics to try and defy

due to gravity‚ g the acceleration due to gravity‚ G the Universal Gravitational Constant (6.67x10-11 N.m2/kg2)‚ m the mass and rthe distance between two objects. Then F = G m1 m2 / r2 Acceleration due to gravity outside the Earth It can be shown that the acceleration due to gravity outside of a spherical shell of uniform density is the same as it would be if the entire mass of the shell were to be concentrated at its center. Using this we can express the acceleration due to gravity (g’) at

subject only to the earth’s gravitational field. To prove the law of conservation of energy‚ the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time‚ velocity of the object vs. time‚ and acceleration of the object vs. time. It is observed in this ball toss experiment‚ at any point during the free fall period‚ the system contains the same total amount of mechanical energy. This amount is the sum of kinetic and gravitational potential energy
