  • Understanding Velocity: The 3 Key Factors
    You need to know these three things to determine velocity:

    1. Displacement: This is the change in position of an object. It's not just the distance traveled, but also the direction. Think of it like a straight line from the starting point to the ending point.

    2. Time: This is the duration over which the displacement occurred.

    3. Direction: This is the specific path or orientation the object took during its displacement.

    Here's how they come together:

    Velocity is calculated by dividing the displacement by the time taken. It's a vector quantity, meaning it has both magnitude (speed) and direction.

    Example:

    * You walk 10 meters east (displacement) in 5 seconds (time).

    * Your velocity is 10 meters/5 seconds = 2 meters per second east.
