ICSE CLASS 9 | CHAPTER 2 MOTION IN ONE | NUMERICALS - Ex - 2a |SELINA - CONCISE PHYSICS ================================ In this short you will find Solved Numericals of Exercise 2a Chapter 2 Motion in one dimension. Class 9 Concise physics SELINA publications Key concepts for motion in one dimension, also known as linear or rectilinear motion, include the variables, mathematical tools, and specific types of movement used to describe objects traveling along a straight line.  Core concepts Kinematics: The branch of classical mechanics that describes the motion of objects without considering the forces that cause the motion. Linear motion / Rectilinear motion: The movement of an object along a single straight line. Reference point / Origin: A fixed point used to determine an object's position. Free fall: The motion of an object under the sole influence of gravity, considered a case of one-dimensional motion.  Variables and quantities Position : An object's location at a specific time relative to the origin. Time: The interval over which motion occurs; a scalar quantity. Displacement : The change in an object's position, representing the shortest distance between its initial and final points. It is a vector quantity, meaning it has both magnitude and direction, indicated by a positive or negative sign. Distance: The total path length an object travels, regardless of direction. It is a scalar quantity and is always positive. Velocity : The rate of change of displacement. As a vector, it can be positive, negative, or zero.Initial velocity The velocity at the beginning of a time interval. Final velocity The velocity at the end of a time interval.Average velocity: The total displacement divided by the total time taken. Instantaneous velocity: The velocity of an object at a single, specific moment in time.Speed: The magnitude of velocity. It is a scalar quantity. Acceleration : The rate of change of velocity. A vector quantity that can be constant or changing.  Equations and formulas Kinematic equations: A set of formulas used to analyze motion with constant acceleration. Graphical analysis  Position-time graph: Slope: Represents the object's velocity. Straight line: Indicates constant velocity. Velocity-time graph:Slope: Represents the object's acceleration. Area under the curve: Represents the object's displacement. Acceleration-time graph:Area under the curve: Represents the change in the object's velocity.  ================================ #trending #shorts #shortvideo #short #yt #youtube #class9 #icse #cbse #ncert #exam #exams #learning is fun #physics #science #chemistry #biology #neet #astronomy #physicsmemes #space #education #mathematics #engineering #maths #math #nasa #astrophysics #physicsfun #quantumphysics #universe #scientist #sciencememes #memes #cosmos #technology #physicsclass #aiims #jee #physicsfacts #sciencefacts #cosmology #cbse
