Distance and Displacement

Front

What is the definition of distance?

Back

Distance is the total length of the path traveled by an object, regardless of direction.

Front

What is the definition of displacement?

Back

Displacement is the change in position of an object, measured as the shortest straight line from the initial position to the final position, along with the direction.

Front

If David walks 3 km north and then 4 km east, what is the total distance he walked?

Back

7 km

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that measures the total path length, while displacement is a vector quantity that measures the shortest path between two points.

Front

What is the formula for calculating displacement?

Back

Displacement = Final Position - Initial Position.

Front

If an object returns to its starting point, what is its displacement?

Back

0 m, because the initial and final positions are the same.

Front

What is a reference point in motion?

Back

A reference point is a stationary object or location used to determine the position of another object.

Front

If Jerry walked 5 km to school and then 3 km to the park, what is his total distance?

Back

8 km

Front

If Jerry's home is at point A, school at point B, and park at point C, what is his total displacement if he returns home?

Back

0 km, because he ends up at the starting point.

Front

What is the significance of direction in displacement?

Back

Direction is crucial in displacement because it indicates the shortest path from the initial to the final position.
