linear motion physics notes

Physics Study Notes Lesson 4 Linear Motion Mr. Lin 2 b. A body falling freely in a vacuum starts from an initial velocity zero and accelerates at approximately 9.8ms. The three equations of linear motion hold for motions under the influence of gravity. While formulae can be used to calculate motion, it can be useful to visualize an object’s motion by looking at a graph.!! Motion in a Straight Line NCERT Solution Motion in a Straight Line. A ticker timer is used to measure a short period of time in linear motion. After attaining the maximum height, the body then falls back with an increasing velocity. endobj OA implies uniform motion with constant speed as the slope is constant; AB implies the body is at rest as the slope is zero; B to C is non-uniform motion; To know more about Distance-Time Graph, visit here. Law of Motion Class 11 Notes Physics Chapter 5 • Dynamics is the branch of physics in which we study the motion of a body by taking into consideration the cause i.e., force which produces the motion. STAGE 1 PHYSICS TOPIC 1: LINEAR MOTION AND FORCES The equation for calculating speed is speed = distance time Using symbols we write v = s t Where v = speed, s = distance and t = time. Motion in a Straight Line Class 11 Physics Formulas. Calculate the time taken before the two objects meet. Chapter 3: Linear Motion Preliminaries • Linear motion is motion in a straight line. For example, you predict where obstacles will be at later ti mes. These are the Law of Motion class 11 Notes prepared by team of expert teachers. Rest If an object does not change its position with respect to its surroundings with time, then it is called at rest. Form Three Physics revision questions on all topics including Linear Motion, Refraction of Light, Newtons Law of Motion, Work, Energy, Power and Machines Current Electricity II, Waves II, Electrostatics II, Heating Effect of Electric Current, Quantity of Heat, Gas Laws and more. In this case, the air resistance is assumed to be negligible. Uniform linear motion with constant velocity or zero acceleration 2. the time taken for the stone to strike the ground. %PDF-1.4 For real objects (which are not mathematical points), translational kinematics describes the motion of an object's center of mass through space, while angular kinematics describes how an object rotates about its centre of mass.

We can divide vectors into parts called "components", of which the vector is a sum. With the help of a stop watch, measure and record the time for ten oscillations (allow some little oscillations after release before timing).

Average velocity: € averagevelocity= totaldisplacement timeinterval € v = d t, € v = average velocity (m/s) d = total displacement (m) t = time interval (s) c. Displacement is a vector quantity; its magnitude is the straight-line distance between the initial What is the acceleration produced? Displace the bob sideways through a small angle of about 2 0 and release it so as to oscillate.

When a body is projected vertically upwards, it decelerates uniformly due to gravity until its velocity reduces to zero at maximum height. Lecture Video: Linear Motion Equations. Dynamics. HTML code is not allowed. Velocity-time graphs examine a changing velocity over time.! Equations of motion for constant acceleration between two points. The slope of a displacement-time graph gives the velocity of the body. Physics Notes Class 11 CHAPTER 5 LAWS OF MOTION Inertia The property of an object by virtue of which it cannot change its state of rest or of uniform motion along a straight line its own, is called inertia. <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/StructParents 0>> Position-time graphs show how position changes over time.! Description. In Physics Notes Class 11 CHAPTER 3 MOTION IN A STRAIGHT LINE Motion If an object changes its position with respect to its surroundings with time, then it is called in motion. endobj Wednesday, April 28, 2010 | By admin Linear Motion. They are nearly all vectors. 11 Physics notes Chapter 5 Law of Motion. Graphical Representation of Motion. Chapter 9 9.1 Action of Forces and Torques on Rigid Objects Most rigid objects (i.e. thus the three equations become: A hammer falls from the top of a building 5m high. In this branch of physics, we deal with the motion of an object. L�Y���&˩�Q?zx�axM�� Problems from Physics, Chapter No.3 (kinematics Of Linear Motion) for Class 10th, X, SSC Part 2, Matric. Hence calculate the period T(time for one oscillation). In physics, a vector often describes the motion of an object. Start revising A-level & GCSE with 7 million other students. CBSE ICSE Select Class Class 6 Class 7 Class 8 Class 9 Class 10. Answers of assignment are given at the end of each assignment with complete solutions.

Linear motion: Rectilinear motion: An object is said to be in a linear motion when the object moves in a straight line: An object is said to be in a rectilinear motion when two objects are moving in a straight line and are parallel to each other: There are two types of linear motion, and they are uniform motion and non- uniform motion You can play, replay and pause the lecture to take down notes. Physics Study Notes Lesson 4 Linear Motion Mr. Lin 1 1 Change and Motion a. If the velocity of a body decreases with time, its acceleration becomes negative. The study of motion is divided into two areas namely kinematics and dynamics. Many people are afraid of physics because it relies heavily on mathematics, but don’t let this deter you.

The motion of a point particle is fully described using three terms - position, velocity, and acceleration. Purchase to access the complete document. unit 1: linear motion Every time you catch a ball, ride a bike, or lift a bag, you are using physics to make predictions without realizing it. Video lectures on SHS 1 Physics are now available. Distance is the total length of the path traveled by an object. A particle travelling in a straight line at 2m/s is uniformly accelerated at 5m/s. Welcome to your Physics class. Distance-Time Graph. At what height above the point of projection do they meet? Therefore, in the three equations of linear motion u=0m/s, s=h and a=g.
