FAQs on Quick Revision: Motion in a Straight Line - Physics Class 11 - NEET

1. What is motion in a straight line?
Ans. Motion in a straight line refers to the movement of an object along a path without any change in its direction. It can be described by its position, velocity, and acceleration.
2. What is the difference between speed and velocity in motion?
Ans. Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that not only measures the speed but also includes the direction of motion.
3. How can we calculate the average velocity of an object in motion?
Ans. The average velocity of an object can be calculated by dividing the total displacement by the total time taken. It is given by the formula: average velocity = (final position - initial position) / time.
4. What is the difference between uniform motion and non-uniform motion?
Ans. Uniform motion is when an object covers equal distances in equal intervals of time, while non-uniform motion is when an object covers unequal distances in equal intervals of time or equal distances in unequal intervals of time.
5. What is the significance of the slope of the distance-time graph in motion?
Ans. The slope of the distance-time graph represents the speed or velocity of the object in motion. A steeper slope indicates a higher speed, while a flat slope indicates a lower speed or no motion.
