Displacement:
The term displacement refers to a physical quantity that measures the change in position of an object or a point from its initial position to its final position in a given direction.
Key Points:
- Physical Quantity: Displacement is a vector quantity as it has both magnitude and direction.
- Change in Position: Displacement is concerned with the overall change in position and does not account for the path taken to reach the final position.
- Initial and Final Position: Displacement is calculated by considering the coordinates or location of an object or a point at the initial and final moments of time.
- Direction: Displacement specifies the straight line distance and the direction needed to reach the final position from the initial position.
Formula for Displacement:
The displacement (d) can be calculated using the following formula:
d = final position – initial position
Units of Displacement:
The SI unit of displacement is the meter (m). However, other commonly used units include kilometers, miles, feet, and centimeters.
