Easy to print and read. ; Distance and time are important factors to consider motion. Since, the velocity of the object is not constant, therefore, it possesses acceleration. You learnt that a motion could be along a straight line, it could be circular or periodic. Equation of motion for uniform motion : Distance/Displacement = speed × time = velocity × time Note: For uniform motion along a straight line, speed and velocity are same. Fundamental physical quantity : The physical quantities which are independent of other physical quantities are called fundamental physical quantities. 1. Slow and Fast Motion: If an object A covers more distance and object B covers less distance in same time, then object A is called in Fast Motion and object B is called in Slow Motion. Table 13.1 gives some common examples of motions. Scalars: The quantities which have magnitude only are called scalars. Motion and Time I n Class VI, you learnt about different types of motions. Class 7 Science Motion and Time Chapter Notes. (ii) Non-uniformly accelerated miotion : Where the acceleration of the body keeps on changing with time. (a) The motion is said to be a uniform motion (b) The motion is said to be a non uniform motion (c) The object is said to be stationary (d) The motion is said to be a fast motion Q6: The motion that repeats itself after regular intervals of time can be ___ (Find the incorrect option). Vectors: The quantities which have magnitude as well as directions both are called vectors. The basic unit of time is a second. All physical quantities can be categorised into scalars and vectors. (a) To and Fro Motion (b) Circular Motion (c) Rectilinear Motion Use them for better understanding of the subjects. Physics Motion and Time Part 1 (Motion & Examples) Class 7 VII.

Motion is a change in position of an object with respect to time .If the position of a body is not changing with respect to time, the body is said to be at rest, motionless, immobile or stationary.Any moving body is said to be in motion.Some types of motions are show below: Class 9 Science Chapter 8 Motion Notes - PDF Notes Motion Class 9 Notes aims at increasing your self-confidence and reducing the pressure by offering a simple way to study or revise the chapter. Thus Speed = Total distance covered/ Total time taken The S.I. These notes are prepared by our panel of highly qualified teachers, out of the past 10 years question papers so that the students don’t miss out on any of the important topics. Answer: Metre / second is the basic unit of speed. Motion: A body is said to be in motion if it changes its position with respect to time with respect to another body. Uniform motion: When an object moving along a straight line moves with a constant speed, then the object is said to be in uniform motion. Students can download these useful educational material free and use them to get better marks in examinations. Physics Motion and Time Part 1 (Motion & Examples) Class 7 VII.
