What is the definition of displacement?
What is the definition of displacement?
- The distance an object has traveled in total
- The force acting on an object in motion
- The change in an object's position and direction from the starting point (correct)
- The speed at which an object is moving
In which situation would an object have zero displacement but a non-zero distance?
In which situation would an object have zero displacement but a non-zero distance?
- An object moving in a circular path and returning to its starting point (correct)
- An object moving back and forth along the same path
- An object moving in a straight line away from its starting point
- An object moving in a straight line back to its starting point
How is displacement different from distance?
How is displacement different from distance?
- Displacement is always greater than distance
- Displacement considers the actual path taken, while distance does not (correct)
- Displacement is a scalar quantity, while distance is a vector quantity
- Displacement is measured in kilometers, while distance is measured in meters

Study Notes
Displacement Definition
- Displacement is a measure of the net change in an object's position from its initial to its final position.
Displacement vs. Distance
- Displacement is different from distance, as distance is a measure of the total amount of ground covered by an object, regardless of its direction.
- An object can have a non-zero distance but a zero displacement if it returns to its initial position.
- Example: A car traveling in a circular path returns to its starting point, having zero displacement but a non-zero distance (the circumference of the circle).
