Step 1:I'll solve this problem step by step:
Step 2:: Understand the Concept of Rolling Traction
Rolling traction refers to the friction between a tire and the road surface that allows a vehicle to move forward without slipping. This occurs when the tire rotates and maintains contact with the road surface without sliding.
Step 3:: Analyze the Definition of Rolling
In true rolling motion, the point of contact between the tire and the road momentarily has zero velocity relative to the road surface. This means the tire is gripping the road and rotating without sliding.
Step 4:: Evaluate the Statement
The statement suggests that rolling traction involves tire sliding across the road. However, this is incorrect. Sliding would actually indicate a loss of traction, not the proper rolling motion.
Step 5:: Determine the Correct Answer
Since sliding contradicts the fundamental principle of rolling traction, the statement is false.
Final Answer
False Explanation: Rolling traction occurs when a tire rotates and maintains grip with the road surface without sliding. When tires slide across the road, it indicates a loss of traction, which is the opposite of proper rolling motion. Therefore, the statement that "Rolling traction is demonstrated when tires slide across the road" is false.
