Olympiad Test: Motion and Measurement of Distances - Question 1

Prem and Raju started walking from their house to reach their friend Ritika's house. Prem covered a distance of 2 km and Raju covered a distance of 4 km but they both took the same time. Which among the following statements is correct for the above situation?

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 1

let suppose they both took 1hrs.
Prem covered distance = 2km
prem's speed = 2km / hr
Raju covered distance = 4km
raju's speed = 4km / hr
so from here , it is clear that raju covered 4km with speed of 4km/hr which is more than prem by distance and speed.

Olympiad Test: Motion and Measurement of Distances - Question 2

Which of the following statements is correct for measuring the length using a ruler?

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 2

Accuracy in measurement using a ruler is essential. Keeping your eye vertically above the point where the measurement is taken reduces parallax error, ensuring precise measurements.

Olympiad Test: Motion and Measurement of Distances - Question 3

Which of the following is not an example of rotational motion?

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 3

The movement of a person on the road is an example of linear motion, not rotational motion.

Olympiad Test: Motion and Measurement of Distances - Question 4

Match the following:

Olympiad Test: Motion and Measurement of Distances - Question 5

A car covers a distance of 40 km in first hour and 50 km in the second hour. Which type of motion is this?

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 5

The motion described in the scenario is an example of non-uniform motion.
Non-uniform motion occurs when an object travels unequal distances in equal intervals of time. In this case, the car covers a distance of 40 km in the first hour and 50 km in the second hour. The distances covered in each hour are different, indicating that the car is not moving at a constant speed. If it were moving at a constant speed, it would cover the same distance in each hour.
Uniform motion, on the other hand, would involve the object covering equal distances in equal intervals of time. Periodic motion refers to motions that repeat at regular intervals, like the motion of a pendulum. Rotational motion involves objects spinning or rotating around an axis, which is not described in the given scenario. Therefore, the correct answer is B) Non-uniform motion.

Olympiad Test: Motion and Measurement of Distances - Question 6

One gram has been divided into 1000 equal parts, each part is equal to:

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 6

Given that a gram has been divided into 1000 equal parts, each part would be equal to one milligram (option C).
Here's the breakdown of metric units of mass:

  • 1 kilogram (kg) = 1000 grams (g)
  • 1 gram (g) = 1000 milligrams (mg)

Therefore, dividing a gram into 1000 equal parts results in each part being equal to one milligram.

Olympiad Test: Motion and Measurement of Distances - Question 7

Distance from place X to Y is 45 metre and time taken by a person to cover this distance is 9 seconds. The speed of that person in km/h is:

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 7

To find the speed of the person in kilometers per hour (km/h), we can use the formula for speed:

Given:
Distance = 45 meters
Time = 9 seconds
Firstly, we need to convert the distance from meters to kilometers and time from seconds to hours because the answer is required in km/h.
1 kilometer = 1000 meters (conversion factor)

1 hour = 3600 seconds (conversion factor)

Now, let's use the formula for speed:

Therefore, the speed of the person covering the distance from X to Y is 18 km/h (option A).

Olympiad Test: Motion and Measurement of Distances - Question 8

A truck is moving with a uniform speed of 40 km/h. Which of the following graphs is showing the speed of truck?  

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 8

correct answer is C. As the truck is moving with a uniform speed , so it will cover equal distances in equal time intervals which is represented by a straight line on Distance -Time Graph.

Olympiad Test: Motion and Measurement of Distances - Question 9

The following graph is showing:

Detailed Solution for Olympiad Test: Motion and Measurement of Distances - Question 9

As the Y- coordiante is constant , so there is no change in distance , so body is at rest

Olympiad Test: Motion and Measurement of Distances - Question 10
