What is Displacement?

Displacement refers to the change in the position or location of an object or a point in space, measured from a reference point or starting position. It is a vector quantity, which means it has both magnitude (the distance covered) and direction (the path taken). Displacement is used in physics and engineering to describe the change in an object’s position over time.

Key points about displacement include:

1. Vector Quantity: Displacement is a vector because it has both magnitude and direction. This means that not only the distance matters but also the specific path or route taken to get from one point to another.
2. Reference Point: Displacement is measured relative to a reference point or a starting position. It tells you how far and in which direction an object has moved from this reference point.
3. SI Unit: The SI (International System of Units) unit for displacement is the meter (m) since it represents a change in position in three-dimensional space. In one-dimensional motion (e.g., along a straight line), displacement can be measured in meters as well.
4. Positive and Negative Displacement: Displacement can be positive, negative, or zero, depending on the direction of motion. Positive displacement indicates movement in one direction, while negative displacement implies movement in the opposite direction. Zero displacement means no net change in position.

All Formulae Related to Displacement

Displacement is a vector quantity that represents the change in the position of an object or point in space. Here are some key formulae related to displacement:

1. Displacement Formula (Vector Form):
   • Displacement (Δr or 𝐝) = Final Position (𝐫_f) – Initial Position (𝐫_i)
   • Δr = 𝐫_f – 𝐫_i
   • This formula gives the vector displacement, which has both magnitude and direction.
2. Displacement Magnitude:
   • The magnitude of displacement (|Δr| or |𝐝|) is the absolute value of the vector and represents the shortest distance between the initial and final positions.
   • |Δr| = |𝐫_f – 𝐫_i|
3. Displacement in One Dimension:
   • In one-dimensional motion along a straight line, the displacement (Δx) is given by:
   • Δx = x_f – x_i
   • Where Δx is the displacement, x_f is the final position, and x_i is the initial position.
4. Average Displacement (Vector Form):
   • The average displacement (Δr_avg) over a period of time (Δt) is calculated as:
   • Δr_avg = (𝐫_f – 𝐫_i) / Δt
5. Instantaneous Displacement (Vector Form):
   • The instantaneous displacement at a specific time (t) is given by:
   • Δr_instantaneous = 𝐫(t) – 𝐫_i
   • Where 𝐫(t) represents the position of the object at time t.
6. Average Speed (Scalar Quantity):
   • Average speed (v_avg) is defined as the total distance traveled (d_total) divided by the total time (Δt_total) taken:
   • v_avg = d_total / Δt_total
7. Average Velocity (Vector Quantity):
   • Average velocity (𝐯_avg) is calculated as the total displacement (Δr) divided by the total time (Δt) taken:
   • 𝐯_avg = Δr / Δt
8. Instantaneous Velocity (Vector Quantity):
   • The instantaneous velocity at a specific time (t) is given by the derivative of the position vector 𝐫(t) with respect to time:
   • 𝐯_instantaneous = d𝐫/dt
