Explanation:
In the case of uniform motion in a straight line, the average speed of a moving object is the same as the actual speed of the object. This is because the object covers equal distances in the same intervals of time.
Reasons:
There are two main reasons for this:
1. Equal distances: In uniform motion, the object covers equal distances in the same intervals of time. This means that for every unit of time, the object moves the same distance. For example, if the object moves 10 meters in 1 second, it will also move 10 meters in the next second, and so on. This ensures that the average speed, which is calculated by dividing the total distance traveled by the total time taken, is the same as the actual speed of the object.
2. Constant speed: In uniform motion, the object moves at a constant speed. This means that the object covers the same distance in equal intervals of time, regardless of the length of the interval. Even in very small intervals of time, the object will cover the same distance. This again ensures that the average speed is the same as the actual speed of the object.
Example:
Let's consider an object that covers a distance of 100 meters in 10 seconds. The average speed can be calculated by dividing the total distance (100 meters) by the total time (10 seconds), which gives us an average speed of 10 meters per second. In this case, the actual speed of the object is also 10 meters per second because it covers equal distances in the same intervals of time.
Therefore, option A is correct as both reasons mentioned above are correct. The object covers equal distances in the same intervals of time, ensuring that the average speed is the same as the actual speed of the object in uniform motion in a straight line.
