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

1. What is the definition of motion in a straight line?
Ans. Motion in a straight line refers to the movement of an object along a straight path. It is characterized by the object's position changing with respect to time, and can be described using concepts such as displacement, velocity, and acceleration.
2. What are the key equations of motion used in straight-line motion?
Ans. The key equations of motion for straight-line motion are as follows: 1. v = u + at 2. s = ut + ½at² 3. v² = u² + 2as Where: - v = final velocity - u = initial velocity - a = acceleration - t = time - s = displacement These equations help to relate the different parameters of motion.
3. How is acceleration defined in the context of motion in a straight line?
Ans. Acceleration is defined as the rate of change of velocity of an object with respect to time. It can be calculated using the formula: a = (v - u) / t Where: - a = acceleration - v = final velocity - u = initial velocity - t = time taken for the change in velocity. Acceleration can be positive (speeding up) or negative (slowing down).
4. What is the difference between speed and velocity?
Ans. Speed is a scalar quantity that refers to how fast an object is moving, regardless of its direction. It is calculated as the distance traveled over time. Velocity, on the other hand, is a vector quantity that includes both the speed of the object and the direction of its motion. Thus, while speed can be represented simply as a numerical value, velocity must also indicate the direction.
5. How do you graphically represent motion in a straight line?
Ans. Motion in a straight line can be graphically represented using a distance-time graph. In this graph, the x-axis represents time and the y-axis represents distance. A straight line on this graph indicates uniform motion, while a curved line indicates non-uniform motion. The slope of the line gives the speed of the object: a steeper slope means higher speed, while a flat line indicates that the object is at rest.
