Motion is a change in an objects POSITION
A change in that (position) over time is?
Is velocity correct ?
A change in an object's position over time is referred to as displacement. Displacement is a measure of how far an object has moved from its starting point in a specific direction. It involves comparing the object's final position to its initial position.
To calculate displacement, you need to know the initial position (also called the reference point), the final position, and the direction of motion. The direction is typically determined by using a coordinate system, such as the x and y axes, or by indicating specific angles or directions (e.g., north, east, up, etc.).
The formula for displacement is:
Displacement = Final Position - Initial Position
For example, if an object starts at position 3 meters and moves to position 8 meters in the positive x-direction, the displacement would be:
Displacement = 8 meters - 3 meters
Displacement = 5 meters
Therefore, the displacement of the object would be 5 meters in the positive x-direction.
