b) what evidence can you take from the graph to support your claim?
c) write a response that summarizes your claim and evidence as well as supplying your reasoning for why that claim is correct.

Explanation:

Since the problem is about making a claim, finding evidence from a bar - graph related to friction acting on a skateboarder and writing a summary with reasoning, it involves analysis and explanation in the context of a physical phenomenon. Friction is a key concept in Physics. We need to observe the graph to identify trends or values that support a claim about friction. For example, if the graph shows how different surfaces affect the speed or distance traveled by the skateboarder, we can claim that friction is higher or lower on certain surfaces based on the data presented in the graph. The reasoning would involve the principles of friction such as how it opposes motion and how surface characteristics influence its magnitude.

Answer:

a) A possible claim could be: "The friction acting on the skateboarder is higher on the rough - textured surface compared to the smooth surface."
b) Evidence from the graph could be that the skateboarder travels a shorter distance or has a lower speed on the bar representing the rough - textured surface compared to the smooth surface bar.
c) Reasoning: Friction is a force that opposes motion. Rougher surfaces have more irregularities, which create more resistance against the motion of the skateboarder's wheels, thus increasing the friction and reducing the distance or speed traveled. A summary response could be: "The claim that friction is higher on the rough - textured surface for the skateboarder is supported by the graph data showing a shorter distance or lower speed on that surface. This is because rough surfaces have more irregularities that increase the resistance to the skateboarder's motion, in accordance with the principles of friction."
