FAQs on What is Uniform and Non-Uniform Motion? Video Lecture - Science Class 7

1. What is the definition of uniform motion?
Ans. Uniform motion refers to the motion of an object traveling at a constant speed in a straight line. In this type of motion, the distance covered by the object in equal intervals of time remains the same. For example, if a car moves at a steady speed of 60 km/h on a straight highway, it is in uniform motion.
2. How does non-uniform motion differ from uniform motion?
Ans. Non-uniform motion is characterized by a change in speed or direction over time. Unlike uniform motion, where the speed and direction remain constant, an object in non-uniform motion may accelerate, decelerate, or change its path. For instance, a car that speeds up, slows down, or turns while driving is exhibiting non-uniform motion.
3. What are some real-life examples of uniform motion?
Ans. Real-life examples of uniform motion include a train moving at a constant speed on straight tracks, a bicycle traveling at a steady pace on a flat road, or a person walking at a consistent speed on a treadmill. In each case, the distance covered over equal time intervals remains unchanged.
4. Can you provide examples of non-uniform motion?
Ans. Non-uniform motion is observed in various scenarios, such as a roller coaster ride where the car speeds up and slows down on different parts of the track, a car stopping and starting in traffic, or a soccer ball being kicked and changing its speed and direction. These examples illustrate how the motion can vary over time.
5. How can one calculate the speed in uniform and non-uniform motion?
Ans. In uniform motion, speed can be calculated using the formula: Speed = Distance/Time. For non-uniform motion, the average speed can be calculated using the same formula, but it may require measuring the total distance traveled and the total time taken, as the speed may vary at different intervals. To analyze non-uniform motion in more detail, one may use graphs or calculus to determine instantaneous speeds at various points.
