Explanation:

Since the article is not provided, I'll give a general example of how to approach this using physics concepts (Newton's second law, \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration, and acceleration is related to motion change).

1. Identify Relevant Physics Concepts: The claim relates to Newton's second law (\( F = ma \)) and how force and mass affect motion (via acceleration, which changes velocity).
2. Hypothetical Evidence Example: Suppose the article states: "When a 2 N force is applied to a 1 kg cart, it accelerates at 2 m/s²; when the same 2 N force is applied to a 2 kg cart, it accelerates at 1 m/s²."
3. Explain Support: This evidence shows that for the same force, a larger mass (2 kg vs. 1 kg) results in smaller acceleration (slower change in motion). Also, if the article says "Increasing the force on a 1 kg cart from 2 N to 4 N makes its acceleration double (from 2 m/s² to 4 m/s²)", this shows force directly affects acceleration (and thus motion). Both examples link force/mass to motion via acceleration, supporting the claim.

To answer fully, you would:

• Quote the specific evidence from the article (e.g., experimental data, descriptions of forces/mass affecting motion).
• Connect the evidence to the claim using physics principles (e.g., \( F = ma \), how acceleration (a) changes velocity (motion) over time, and how \( F \) or \( m \) alter \( a \)).

For example, if the article has an experiment with toy cars:
Evidence: "When we pushed a light toy car (small mass) with a strong force, it sped up quickly (large acceleration, so motion changed rapidly). When we pushed a heavy toy car (large mass) with the same strong force, it sped up more slowly (smaller acceleration). When we pushed the light car with a weak force, it sped up slowly."

*: This shows that (1) larger mass (heavy car) with the same force leads to less acceleration (slower motion change), and (2) smaller mass (light car) with stronger force leads to more acceleration (faster motion change). Thus, force and mass both impact the object’s motion (via acceleration), supporting the claim.

Answer:

*: This shows that (1) larger mass (heavy car) with the same force leads to less acceleration (slower motion change), and (2) smaller mass (light car) with stronger force leads to more acceleration (faster motion change). Thus, force and mass both impact the object’s motion (via acceleration), supporting the claim.
