Uniform motion vs Non-uniform motion
Uniform motion refers to the motion of an object where it covers equal distances in equal intervals of time. On the other hand, non-uniform motion refers to the motion of an object where it covers unequal distances in equal intervals of time.
Analysis of the given scenario
Let's analyze the given scenario step by step to determine whether the motion of the car is uniform or non-uniform.
1. In the first hour, the car travels a distance of 60 km.
2. In the second hour, the car travels a distance of 70 km.
3. In the final hour, the car travels a distance of 20 km.
Calculating the time intervals
To determine whether the distances covered by the car are equal or not, we need to calculate the time intervals for each distance.
1. The car covers the first 60 km in 1 hour, so the time interval for this distance is 1 hour.
2. The car covers the next 70 km in the next hour, so the time interval for this distance is also 1 hour.
3. The car covers the remaining 20 km in the final hour, so the time interval for this distance is again 1 hour.
Comparing the distances covered
Now, let's compare the distances covered by the car in each time interval.
1. In the first hour, the car covers 60 km.
2. In the second hour, the car covers 70 km.
3. In the final hour, the car covers 20 km.
Conclusion
From the analysis, we can see that the car covers unequal distances in equal intervals of time. Therefore, the motion of the car is non-uniform.
Explanation of the correct answer
The correct answer is option 'B' - non-uniform motion. This is because the car covers unequal distances (60 km, 70 km, and 20 km) in equal intervals of time (1 hour each). In uniform motion, the distances covered by an object in equal intervals of time would be the same.
Uniform motion refers to the motion of an object where it covers equal distances in equal intervals of time. On the other hand, non-uniform motion refers to the motion of an object where it covers unequal distances in equal intervals of time.
