Motion is change in position of an object with time. How does the position change with time ? In this chapter , we shall learn how to describe motion. For this, we develop the concepts of velocity and acceleration. We shall confine ourselves to the study of motion of objects along a straight line, also known as rectilinear motion. For the case of
learn how to describe motion. For this, we develop the concepts of velocity and acceleration. We shall confine ourselves to the study of motion of objects along a straight line, also known as rectilinear motion. For the case of rectilinear motion with uniform acceleration, a set of simple equations can be obtained. Finally, to understand the ...
What is a vector? How to add, subtract and multiply vectors ? What is the result of multiplying a vector by a real number ? We shall learn this to enable us to use vectors for defining velocity and acceleration in a plane. We then discuss motion of an object in a plane.
The NCERT Solutions for Class 11 Physics Chapter 3 Motion in a Straight Line provides students with simple and stepwise answers to the questions present in the textbook. The solutions are helpful in understanding the method of answering the questions in the exams.
In which of the following examples of motion, can the body be considered approximately a point object. (a) A railway carriage moving without jerks between two stations. (b) A monkey sitting on top of a man cycling smoothly on a circular track. (c) A spinning cricket ball that turns sharply on hitting the ground.
Types of Motion. 1. One Dimensional Motion. If only one out of three coordinates specifying the position of the object changes with respect to time, then the motion is called one dimensional motion. ev. l and narrow road and . 2. Two Dimensional Motion.
Question 4. 1. State, for each of the following physical quantities, if it is a scalar or a vector: volume, mass, speed, acceleration, density, number of moles, velocity, angular frequency, displacement, angular velocity. Answer: Scalars: Volume, mass, speed, density, number of moles, angular frequency.
