FAQs on NCERT Textbook: Motion in a Straight Line - Science & Technology for UPSC CSE

1. What is motion in a straight line?
Ans. Motion in a straight line is a type of motion in which an object moves in a straight line without changing its direction. It is also known as rectilinear motion. The motion of a car moving on a straight road or a ball thrown in a straight line are examples of motion in a straight line.
2. What is the difference between distance and displacement?
Ans. Distance is the total path covered by an object in motion, irrespective of direction. Displacement is the shortest distance between the initial and final position of an object in motion, measured in a straight line. Distance is a scalar quantity, while displacement is a vector quantity as it has both magnitude and direction.
3. What is the formula for average velocity?
Ans. The formula for average velocity is given as the displacement of an object divided by the time taken. It is represented as: Average velocity = (change in displacement) / (time taken) The SI unit of velocity is meters per second (m/s).
4. What is the difference between speed and velocity?
Ans. Speed is the rate at which an object covers a distance. It is a scalar quantity as it has only magnitude and no direction. Velocity, on the other hand, is the rate at which an object changes its position in a particular direction. It is a vector quantity as it has both magnitude and direction.
5. What is the difference between uniform and non-uniform motion?
Ans. Uniform motion is a type of motion in which an object covers equal distances in equal intervals of time. The velocity of the object remains constant during uniform motion. Non-uniform motion is a type of motion in which an object covers unequal distances in equal intervals of time. The velocity of the object varies during non-uniform motion. The motion of a freely falling object is an example of non-uniform motion.
