Question 1: Representing Motion

A motion diagram uses dots (representing the object’s position at equal time intervals) to show motion. For constant speed, dots are equally spaced; for acceleration, spacing changes. It visualizes position, speed, and acceleration over time.

For a bike moving at constant pace (constant speed) along a straight path:

1. Draw a straight horizontal line (path).
2. Place dots (particle model) at equal distances along the line (equal time intervals, constant speed → equal spacing).
3. Label direction (e.g., right) and note constant spacing (no acceleration).

(Diagram sketch: Straight line with equally spaced dots, e.g., •——•——•——•, each “——” represents equal time/distance.)

Answer:

A motion diagram represents an object’s motion by showing its position at equal time intervals (using dots). Spacing between dots indicates speed (equal spacing = constant speed, changing spacing = acceleration), and dot arrangement shows direction/path.
