  • Describing Motion: Key Measurements for Ball Trajectory
    Here are two measurements a student could take to describe the motion of a ball:

    * Position: This tells you where the ball is at a given time. You could describe this using:

    * Distance: How far the ball is from a reference point (e.g., "The ball is 5 meters away from the wall").

    * Coordinates: Using a grid system (like X and Y axes), you can pinpoint the ball's exact location.

    * Time: This tells you when the ball is at a particular position. You could use a stopwatch or clock to record the time.

    By combining these measurements, you can describe the motion of the ball in more detail. For example, you could say "The ball was 5 meters away from the wall at 3 seconds".
