The rate of change of motion of an object can be known by measuring the _____ of the object.

Distance

Time taken

Speed

None of the above

Answer explanation

Rate of change of motion is the speed of an object. It needs both distance and time to be calculated. Hence, option 1 and 2 are wrong. The correct answer is option 3.

A car is covering a distance of 10 metres every 4 seconds along a straight path. Which motion is the car in?

Linear motion

Non−uniform motion

Uniform motion

Both option 1 and 3

Answer explanation

The object is moving in a straight path, so it is in linear motion. Now, the object is also covering equal distance in equal time interval which shows the object is in uniform motion. Hence, option 4 is the correct answer.

A car is covering a distance of 60 km. It covers the first 30 km in 40 minutes and the remaining distance in 20 minutes. What will be the average speed of the car in metre per second?

60 m/sec

16. 6667 m/sec

60km/hr

25 m/sec

Answer explanation

Total distance = 30 km + 30 km = 60 km Total time taken = 40 minutes + 20 minutes = 60 minutes = 1 hour Average speed = Total distance / Total time taken = 60/1 = 60 km/hr Average speed in metre/second = 60 × 1000/3600 = 16.667 m/sec [1 km = 1000 m & 1 hour = 3600 seconds]

Vehicle A covers a distance of 100 km in 2 hours, and vehicle B covers a distance of 300 km in 5 hour. Which vehicle is faster and by how much?

Vehicle A is faster than vehicle B by 10 km/hr

Vehicle B is faster than vehicle A by 10 km/hr

Both vehicles have the same speed

Vehicle B is faster by 60 km/hr

Answer explanation

To find the faster vehicle, we have to find the speed of both the vehicles. Speed of vehicle A = 100/2 = 50 km/hr Speed of vehicle B = 300/5 = 60 km/hr Hence, vehicle B is faster by 10 km/hr.

Which of the following statements is false?

An object in uniform motion covers equal distance in equal interval of time.

The speed of an object is not always constant.

The speed of an object is not constant in uniform motion.

An object with uniform speed is in uniform motion.

Answer explanation

The speed of an object in uniform motion is constant. Therefore option 3 is the correct answer.

Media Image

Look at this image. Here, distance between position A to position B is 100 metres and displacement is half of the total distance. The speed of the car is 4 m/s.What will be the total time taken to reach from position A to position B if the shortest route is taken?

12.5 seconds

50 seconds

25 seconds

None of the above

Answer explanation

Shortest route between two positions is the displacement. So, Time taken = Displacement/ Speed = 1/2 of the total distance/speed = 50/4 = 12.5 seconds Hence, option 1 is correct.
