NCERT Class 7 Science Chapter 9 introduces us to the concepts of motion and time. In this Physics lesson, we begin with definitions of motion and rest followed by the types of motion. Thereafter, we learn about the oscillations of a pendulum. After that, we will dive into definitions, formulae, and measurements of distance, time, and speed. In addition, we also explore measuring devices for distance and speed in a vehicle. To help you get started we have summarised all concepts in simplified form. Additionally, we also provide solutions to all questions following the chapter. <\/p>\n\n\n\n

Introduction to NCERT Class 7 Science Chapter 9: Motion and Time<\/h2>\n\n\n\n

To understand the concepts and formulas in the NCERT Class 7 Science Chapter 9, it is essential to learn about \u201cmotion\u201d and \u201crest. Also, we will explore types of motion. Let us proceed!!<\/p>\n\n\n\n

Motion and Time Class 7 Notes <\/h2>\n\n\n\n

Let us now look at Class 7 Science Chapter 9 Notes. <\/p>\n\n\n\n

Motion<\/h3>\n\n\n\n

An object is considered to be in motion when it alters its location over a period of time. For instance, a car travelling along a roadway.<\/p>\n\n\n\n

Rest<\/h3>\n\n\n\n

An object is considered to be stationary when it remains in the same position over a period of time, like a person standing on the ground.<\/p>\n\n\n\n

Types of Motion<\/h3>\n\n\n\n

There are three types of motion: Rectilinear motion; Circular motion; and Oscillatory motion.<\/p>\n\n\n\n

    \n
  • Rectilinear motion: <\/strong>When an object moves in a straight line without changing its direction, it is described as showing \u201crectilinear motion\u201d. Another name for rectilinear motion is \u201ctranslatory motion\u201d. For example, a train moving on a railway track.<\/li>\n\n\n\n
  • Circular motion:<\/strong> When an object moves in a circular path around a fixed point with a constant radius, it is referred to as being in a state of \u201ccircular motion\u201d. For instance, the movement of the moon around the Earth.<\/li>\n\n\n\n
  • Oscillatory motion:<\/strong> When an object’s motion repeats at consistent time intervals, it is described as periodic or oscillatory motion. For instance, the back-and-forth movement of a simple pendulum.<\/li>\n<\/ul>\n\n\n\n
    Oscillations of a Simple Pendulum: <\/strong>When the bob of a simple pendulum swings from its central position B to point A, then returns to B. The bob then swings from B to point C. Now, it returns to B once more. the pendulum is considered to have completed one oscillation.In the context of a simple pendulum, the time period refers to the entire duration it takes for the pendulum to finish one full oscillation.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
