Question

Average Velocity and Average Speed is the same for which of the following situations:

1) A one-way trip on a straight road.

2) A car making a round trip on a circular track.

3) A bullet travelling in a straight line.

• A. For a flight travelling between Delhi to Kolkata.
• B. A car making a round trip on a circular track.
• C. A single trip on a straight road.
• D. Both option A and C.

Answer 1

The correct option is D

Both option A and C.

For average velocity and average speed to be the same, distance and displacement of the body should be the same. The bullet is travelling in a straingt line and the road-trip is also one-way on a straight road. So its distance and displacement are the same. A car making a round trip on a circular track has zero displacement whereas it will have some non-zero distance.
