Distance vs Displacement

Q.

In which of the following instances would the path length of travel be useful?

1. To determine how much fuel to put in the vehicle

2. To determine how long a journey might take

3. To determine the wear and tear on the vehicle

4. None of these

Q.

An ant moves from A to B then to c, what is the distance (d) and displacement (s) of the ant?

1. d = 3 cm, s = 7 cm

2. d = 7 cm, s = 2 cm

3. d = 7 cm, s = 3 cm

4. d = 8 cm, s = - 3 cm

Q.

Which of the following statements is true?

1. The distance is always greater than the magnitude of displacement

2. The distance is always greater than or equal to the magnitude of displacement

3. The distance is always greater than the displacement

4. The distance is always greater than or equal to the displacement

Q.

An ant moves from A to B. Find the distance (d) and displacement ( s).

1. d = 0 cm, s = 5cm

2. d = 5 cm, s = 0 cm

3. d = 5 cm, s = 5 cm

4. d = 0 cm, s = 0 cm

Q.

An ant moves from A to B and then comes back to point A. Find the distance (d) and displacement (s) of the ant in this entire journey.

1. d = 10 m, s = 0 m

2. d = 0 m, s = 0 m

3. d = 10 cm, s = 10 m

4. d = 5 m, s = 10 m

Q.

In order to find out the amount you must change the time on your clock, which of this is sufficient?

1. The actual longitudes alone of the starting city and the destination city.

2. Only the difference between the latitudes

3. The difference between the longitudes and the direction of travel.

4. The actual latitude and longitude of both the starting and the destination cities.

Q.

In which of the following cases would knowing the path length alone not be enough

1. To determine wear and tear of the tyres.
2. To determine how long the journey would take.

3. Finding out how much fuel a flight journey might require.

4. Determining by how much you must reset your watch.(Change in time zone)

Q. Can I just use the amount I turn my head as the measure for how far a body is moving?

1. No
2. Yes

Q. The distance may or may not be greater than the magnitude of displacement.

1. True
2. False

Q. In order to find out the amount by which you must change the time on your clock, which of this is sufficient?

1. The actual latitude and longitude of both the starting and the destination cities.
2. The actual longitudes alone of the starting city and the destination city.
3. Only the difference between the latitudes.
4. The difference between the longitudes and the direction of travel.
