linear motion physics notes

A ticker timer is used to measure a short period of time in linear motion. Motion in a Straight Line Class 11 Physics Formulas. It consists of an electronic vibrator which makes dots on a moving paper tape attached to the object whose velocity is being measured. 7WII��P���|�/�w�'O��M#�B��e�l�˗�Wtf�����Ry�:�� Linear variation = uniform motion and non-linear variations imply non- uniform motion; The slope gives us speed; Distance – Time Graph. HOME. A paper tape was attached to a moving trolley and allowed to run through a ticker-timer. For example, Warty the Woodchuck goes 10 meters towards a hole in the ground. Good news: you do not have to know this for this class. There are two categories; displacement-time graphs and velocity time graphs. The forum is for further discussions on the lessons. Study of motion is divided into two; 1. �0ݽ>���#�wX�r�3��!����G���_w�����U@��sKl��"yM\�k^���� �ض>^S�j8m�������w�[���넕�ո��HJ}��o��}M���u���D��-ئ�_-���y_Q?&�x/����ﵸ� One dot is the period of time taken between two consecutive dots on a ticker tape. Hence the three equations of linear motion become: From equation (i), the time taken to attain the maximum height is given by; Similarly, the initial velocity u and the maximum height attained by the body h max can be expressed as: When the body finally falls back to its point of projection, the displacement of the body will be zero. This is called the acceleration due to gravity g . The figure below represents part of a tape pulled through a ticker-timer by a trolley moving down an inclined plane. Register Free. ! A-level » Physics » Vectors and Scalars and Linear Motion. To explain or understand the motion of an object we need to introduce some physical quantities, like distance, displacement, speed, velocity, acceleration, momentum, etc are required to explain the linear motion. Many people are afraid of physics because it relies heavily on mathematics, but don’t let this deter you. Designed by the teachers at SAVE MY EXAMS for the CIE AS Physics (9702) syllabus. Welcome to your Physics class. NCERT Solutions. Set the apparatus as shown in the diagram above. QUESTION PAPER. Motion in a Straight Line NCERT Solution Motion in a Straight Line. Only time is a scalar. At the same time, another object is projected vertically upwards with a velocity of 40m/s. Note that all motion is relative i.e the state of a body; at rest or in motion, is ONLY true with respect to the observer’s position. Pls LIKE and SUBSCRIBE it will really mean a lot to us.Thank you so much. A negative acceleration is referred to as. In Linear Motion March 30, 2020 February 2, 2013 by Kinematics is the research regarding the types of movement of an object without referring to … Since a=0 for the horizontal projection, s=R=ut. HTML code is not allowed. A stone falling freely under gravity. A body moves 30m due east in 2seconds, then 40m due north in 4seconds. Share with yours Friends Physics Notes - Practical Centre - Class 10th Graphs of Motion! Distance And Displacement 1. In this branch of physics, we deal with the motion of an object. More Resources. In this topic, we concentrate on linear motion. 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. Rest If an object does not change its position with respect to its surroundings with time, then it is called at rest. Generally, the dots are close together when the velocity is low and wide apart when the velocity is high. You can play, replay and pause the lecture to take down notes. In physics, a vector often describes the motion of an object. Answers of assignment are given at the end of each assignment with complete solutions. Questions / Answers from Physics, Chapter No.3 (kinematics Of Linear Motion) for Class 10th, X, SSC Part 2, Matric. Video lectures on SHS 1 Physics are now available. The motion of the ball is two-dimensional. Ask a question related to this topic in the comment section below. A body covers a distance of 2m in 4seconds, rests for 2seconds and finally covers a distance of 90m in 6seconds. Final Test Kahoot. Displace the bob sideways through a small angle of about 2 0 and release it so as to oscillate. [Rest and motion are relative states. The linear momentum of a particle is defined as the product of the mass of the particle times the velocity of that particle. The motion of the car is one-dimensional. %PDF-1.4
This is because both are acted on by the same gravitational force. Types of Velocity in Physics. With the help of a stop watch, measure and record the time for ten oscillations (allow some little oscillations after release before timing). Free PDF download of Class 11 Physics revision notes & short key-notes for Chapter 7 - Systems of Particles and Rotational Motion to score high marks in exams, prepared by expert Physics teachers from latest edition of CBSE(NCERT) books. 2. Calculate: An object is released to fall vertically from a height of 20m. A jet fighter on practice moving at a velocity of 20m/s released a bomb above the ground which hits the ground after 3s. The spacing between the dots depends on the manner in which the body is moving i.e moving at constant velocity or with increasing velocity or decreasing velocity. The study of motion is divided into two areas namely kinematics and dynamics. Calculate its average speed. v 1 Draw a line through the green point that touches the red curve only once and is perpendicular to the radius of the curve. Problems from Physics, Chapter No.3 (kinematics Of Linear Motion) for Class 10th, X, SSC Part 2, Matric. We will denote vectors with bold letters. Lecture notes for Physics 10154: General Physics I Hana Dobrovolny Department of Physics & Astronomy, Texas Christian University, Fort Worth, TX A graph of T 2 against length l is a straight line through the origin. Then ﬁnd the slope of that line. Motion of objects – living and non-living matter - is one of the key branches of physics. Distance is the total length of the path traveled by an object.

Moving with decreasing velocity (decelerating). It is a vector quantity. 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. It is also called rectilinear or linear motion. Download revision notes for Law of Motion class 11 Notes and score high in exams. We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts. There are three equations governing linear motion. A particle moving with a velocity of 200m/s is brought to rest in 0.02s. Students develop an understanding of motion and waves which can be used to describe, explain and predict a wide range of phenomena. We come across many objects which are moving in a straight line. Physics Study Notes Lesson 4 Linear Motion Mr. Lin 2 b. Visit BYJU’S for chapter wise CBSE notes of all the classes. The three equations of linear motion hold for motions under the influence of gravity. The motion of objects such as car moving on a straight and level road is linear motion. Pages.

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. The various displacement-time graphs are as illustrated below: The slope of a velocity-time graph gives the acceleration of the body. endobj
Equations of motion for constant acceleration between two points. In this graph, distance is taken along the y-axis and time is taken along the x–axis. 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. Ex. Chapter One . <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/StructParents 0>>
If the velocity of a body decreases with time, its acceleration becomes negative. The position change of the object with time in one dimension can be described by only one coordinate. Δx – displacement (m) this is the distance and direction from starting position to ending position. Video lectures on SHS 1 Physics are now available. Consider a body moving in a straight line from an initial velocity u to a final velocity v(u, v≠0) within a time t as represented on the graph below: The slope of the graph represents the acceleration of the body; The area under the graph (area of a trapezium) gives the displacement of the body. Linear motion, motion in one spatial dimension. Shoutbox by SBox. Kindly note that more videos, notes and quizzes will be added to cover the syllabus. Distance is a scalar quantity.
