Distance, Displacement, Speed & Velocity Questions and Answers
- 1.
What does speed indicate in physics?
- A.
Rate of time change
- B.
Distance per time unit
- C.
Displacement per time unit
- D.
None of the above
Correct Answer
B. Distance per time unitExplanation
Speed in physics is defined as the rate at which an object covers distance. It is a scalar quantity, meaning it only has magnitude and no direction. The formula for speed is the total distance traveled divided by the total time taken to travel that distance. Speed provides a measure of how fast something is moving, irrespective of its travel direction, which is essential for understanding motion in everyday contexts and scientific analyses.Rate this question:

What is displacement?
- A.
Total path length
- B.
Shortest path between two points
- C.
Speed over time
- D.
Change in velocity
Correct Answer
B. Shortest path between two pointsExplanation
Displacement refers to the change in position of an object and is a vector quantity, which means it includes both magnitude and direction. It is defined as the shortest path between the starting and ending points. Displacement gives an idea of how far out of place an object is initially and finally, which is crucial in physics for calculating other aspects like velocity.Rate this question:

Which term describes the total path covered?
- A.
Speed
- B.
Velocity
- C.
Distance
- D.
Displacement
Correct Answer
C. DistanceExplanation
Distance is the total path covered by a moving object, regardless of its starting or ending position or the path taken. It is a scalar quantity, meaning it only considers magnitude. Distance is used to describe how much ground an object has covered during its motion and is used in calculating speed but not velocity.Rate this question:

If a car travels in a circular path and returns to the start, what is the displacement?
- A.
Zero
- B.
Equal to the circumference
- C.
Positive
- D.
Negative
Correct Answer
A. ZeroExplanation
When a car travels in a circular path and returns to its starting point, the displacement is zero. Displacement is measured as the shortest path between the initial and final positions. In a complete circle back to the start, these positions are the same, resulting in no displacement, even though a distance was traveled.Rate this question:

How is velocity different from speed?
- A.
It is always slower.
- B.
It is always faster.
- C.
It includes direction.
- D.
It cannot be measured
Correct Answer
C. It includes direction.Explanation
Velocity differs from speed in that it is a vector quantity, which means it includes both a magnitude and a direction. While speed might tell you how fast an object is moving, velocity tells you how fast and in which direction. This distinction is critical for understanding the overall motion of an object in physics, especially when direction changes are involved.Rate this question:

What units are used to measure speed?
- A.
Meters
- B.
Meters per second
- C.
Kilograms
- D.
Seconds
Correct Answer
B. Meters per secondExplanation
Speed is measured in units of distance divided by time, commonly meters per second (m/s) in the metric system. These units provide a measure of how fast an object is moving by stating the distance it travels in a certain amount of time, which is fundamental for many physical calculations and everyday applications.Rate this question:

- 7.
Which scenario describes constant velocity?
- A.
Increasing speed
- B.
Decreasing speed
- C.
Constant speed and direction
- D.
Variable speed
Correct Answer
C. Constant speed and directionExplanation
Constant velocity means that an object is moving at a steady speed in a straight line, hence maintaining both constant speed and constant direction. This scenario is important in physics as it implies no acceleration is occurring, which can simplify many dynamics problems and calculations.Rate this question:
-
- 8.
What does a negative velocity indicate?
- A.
Reversal of time
- B.
Decreasing speed
- C.
Motion in the opposite direction
- D.
None of the above
Correct Answer
C. Motion in the opposite directionExplanation
A negative velocity indicates that an object is moving in the opposite direction to the defined positive direction. In physics, direction is crucial, and defining a negative velocity helps in understanding the actual movement direction relative to a starting point or reference direction, which can be essential in vector analysis and motion studies.Rate this question:

- 9.
How do you calculate average speed?
- A.
Total distance divided by total time
- B.
Total displacement divided by total time
- C.
Maximum speed divided by time
- D.
None of the above
Correct Answer
A. Total distance divided by total timeExplanation
Average speed is calculated by dividing the total distance traveled by the total time taken. This calculation gives a simple but effective understanding of how fast an object moved over a journey, averaging out any variations in speed throughout the trip. It is an important basic measure in both everyday situations and scientific contexts.Rate this question:

What is necessary to determine the velocity of an object?
- A.
Direction only
- B.
Magnitude only
- C.
Both direction and magnitude
- D.
None of the above
Correct Answer
C. Both direction and magnitudeExplanation
To determine the velocity of an object, both its speed (magnitude) and its direction of movement are necessary. Velocity is a vector quantity, and both these components are required to fully describe it. This is crucial for problems in physics where direction influences the outcome, such as collision or trajectory problems.Rate this question:
