Understanding Distance and Displacement

What is the definition of distance?

• Distance is the amount of space between two points.

• Distance is a measure of time taken to travel.

• Distance is the speed at which an object moves.

• Distance refers to the weight of an object.

How is displacement different from distance?

• Displacement is the shortest distance between two points with direction, while distance is the total length of the path traveled without direction.

• Displacement can only be measured in a straight line.

• Displacement measures speed, while distance measures time.

• Distance is always shorter than displacement.

If a person walks 3 km east and then 4 km west, what is their total distance traveled?

• 7 km

• 8 km

• 6 km

• 5 km

What is the displacement of the person in the previous question?

• Displacement is the time taken to reach the final position.

• The displacement is the total distance traveled regardless of direction.

• The displacement is the straight line distance between the initial and final positions.

• Displacement is the average speed of the person during the journey.

Can displacement be zero if distance is not? Explain.

• Displacement is always greater than distance.

• Distance and displacement are always equal.

• Yes, displacement can be zero if distance is not.

• Displacement can never be zero if distance is positive.

What is the formula for calculating displacement?

• Displacement = Final Position x Initial Position

• Displacement = Initial Position / Final Position

• Displacement = Final Position - Initial Position

• Displacement = Initial Position + Final Position

If an object moves in a circular path, what is its displacement after one complete revolution?

• Half the diameter of the circle

• 0

• 1 meter

• Circumference of the circle

What are the units commonly used for measuring distance?

• seconds

• grams

• meters, kilometers, miles, feet, inches

• liters

Is it possible for an object to have a large distance and a small displacement? Give an example.

• A car driving straight for 100 miles and ending at the same point.

• Yes, an example is a person walking in a circle and returning to the starting point.

• A person walking 10 meters in a straight line and stopping there.

• A bird flying in a straight line for 50 meters without returning.

What role does direction play in defining displacement?

• Direction is essential in defining displacement as it determines the vector nature of displacement, indicating the shortest path from start to end.

• Direction only affects speed, not displacement.

• Displacement is only concerned with distance traveled.

• Direction is irrelevant to displacement calculations.
