1. Displacement: This is the change in position of an object. It's not just the distance traveled, but the straight-line distance from the starting point to the ending point, and it includes direction.
2. Time: This is the duration over which the displacement occurred.
3. Direction: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. You need to know the direction of the displacement.
Formula:
Velocity (v) = Displacement (Δx) / Time (Δt)
