Question

1 picturing motion (continued) particle models compare and contrast a motion diagram and a particle model. get it? describe how you would model the motion of the hiker at the beginning of this module. check your progress 1. representing motion how does a motion diagram represent an objects motion? 2. bike motion diagram draw a particle model motion diagram for a bike rider moving at a constant pace along a straight path.

Explanation:

1. A motion diagram shows an object's position at equal - time intervals with arrows representing velocity vectors. A particle model simplifies an object as a point - like particle and focuses on its motion characteristics such as position, velocity, and acceleration.
2. To model the hiker's motion, we could use a motion diagram by marking the hiker's position at regular time intervals and drawing velocity vectors. Or use a particle model to represent the hiker as a particle and analyze its motion parameters.
3. A motion diagram represents an object's motion by showing the object's position at successive equal - time intervals and using arrows to indicate the direction and relative magnitude of the object's velocity at each position.
4. To draw a particle model motion diagram for a bike rider moving at a constant pace along a straight path, mark equally - spaced points along the straight path to represent the bike rider's position at equal time intervals and draw arrows of equal length and in the same direction between consecutive points to represent the constant velocity.

Answer:

1. Motion diagram: shows position at equal - time intervals with velocity vectors; Particle model: simplifies object as a point - like particle for motion analysis.
2. Use motion diagram (mark positions at regular time intervals, draw velocity vectors) or particle model (represent hiker as particle, analyze motion parameters).
3. By showing object's position at successive equal - time intervals and using arrows for velocity.
4. Mark equally - spaced points for positions at equal time intervals, draw equal - length, same - direction arrows for constant velocity.
