Uniform Speed
Uniform speed refers to the motion of an object where it covers equal distances in equal intervals of time. In other words, the speed of the object remains constant throughout its motion.
Explanation:
When a body covers equal distances in equal intervals of time, it means that it is moving at a constant speed. Let's understand this concept in more detail:
- Average Speed: Average speed is calculated by dividing the total distance covered by an object by the total time taken. It is used to represent the overall speed of an object during its motion. However, average speed may not necessarily be constant throughout the entire motion.
- Non-uniform Speed: Non-uniform speed refers to the motion of an object where it covers unequal distances in equal intervals of time. This means that the speed of the object is changing during its motion. For example, if a car starts slow and gradually increases its speed, it is said to be moving with non-uniform speed.
- Uniform Speed: Uniform speed refers to the motion of an object where it covers equal distances in equal intervals of time. This means that the speed of the object remains constant throughout its motion. For example, if a car covers 100 meters in 10 seconds, 200 meters in 20 seconds, and 300 meters in 30 seconds, it is said to be moving with uniform speed.
Example:
Let's consider an example to understand the concept of uniform speed better:
Suppose a car travels a distance of 100 kilometers in 2 hours. In this case, the car covers equal distances of 50 kilometers in each hour. Therefore, the car is moving with uniform speed.
If the car covers 150 kilometers in the next 3 hours, it means that it covers unequal distances of 50, 50, and 50 kilometers in each hour. In this case, the car is not moving with uniform speed as it covers unequal distances in equal intervals of time.
In conclusion, when a body covers equal distances in equal intervals of time, it is said to be moving with uniform speed. This implies that the speed of the body remains constant throughout its motion.
