How can I calculate the magnitude of displacement?

To calculate the magnitude of displacement, you need to know the initial position and the final position of an object or particle. Displacement is a vector quantity, which means it has both magnitude and direction. The magnitude of displacement represents the length or size of the displacement vector.

Here's the formula to calculate the magnitude of displacement:

Magnitude of Displacement = √((Δx)² + (Δy)² + (Δz)²)

Where:

Δx is the difference between the initial and final positions along the x-axis.
Δy is the difference between the initial and final positions along the y-axis.
Δz is the difference between the initial and final positions along the z-axis (applicable in three-dimensional space).
If you are working in two-dimensional space, the formula simplifies to:

Magnitude of Displacement = √((Δx)² + (Δy)²)

To use this formula, ensure that the initial and final positions are measured in the same units (e.g., meters) and that the coordinate axes are consistent.

For example, if an object moves from point A with coordinates (3, 5) to point B with coordinates (8, 10), you can calculate the magnitude of displacement as follows:

Δx = 8 - 3 = 5
Δy = 10 - 5 = 5

Magnitude of Displacement = √((5)² + (5)²) = √(25 + 25) = √50 ≈ 7.07

Therefore, the magnitude of displacement in this example is approximately 7.07 units.
