PPH0075 Physics 1 Chapter 2 __________________________________________________________________________________________ ASD 2008/09 2/ 13 Chapter 2: Kinematics in One Dimension 2.1 Introduction The study of the motion of objects, and the related concepts of force and energy, form the field called mechanics . Mechanics is customarily divided into two parts i.e. kinematics and dynamics . Kinematics : the description of how objects move. ° Kinematics in one dimension : describing an object that moves along a straight line path, which is one dimensional motion . ° Kinematics in two dimensions : the description of the motion of objects that move in paths in two (or three) dimensions . Dynamics : deals with force and why objects move as they do. In this part we will solve the following questions : ° What makes an object at rest begin to move ? ° What causes a body to accelerate or decelerate ? ° What is involved when an object moves in a circle ? We can answer in each case that a FORCE is required. 2.2 Types of motion Translational Rotational Vibrational 2.3 Motion in straight line Vertical Horizontal Slanting 2.4 Reference Frames Any measurement of position, distance or speed must be made with respect to a frame of reference. It is always important to specify the frame of reference when stating a speed. In everyday life, we usually mean " with respect to the Earth ".

PPH0075 Physics 1 Chapter 2 __________________________________________________________________________________________ ASD 2008/09 3/ 13 2.5 Distance and Displacement Distance The length of the actual path or total path length. It depends on the frame of reference, for example, Ipoh is 200 km away from Kuala Lumpur. A set of coordinate axes represents a frame of reference. Displacement The change in position of the object, i.e. displacement is how far the objects is from its starting point.
