When a wheel rolls without slipping, what is the condition for the point of contact with the ground?

Step 1: Understand that a wheel has a point that touches the ground when it rolls.
Step 2: When the wheel rolls without slipping, it means it rolls smoothly without sliding.
Step 3: The point of contact is the exact spot where the wheel meets the ground.
Step 4: For the wheel to roll without slipping, this point of contact must not move forward or backward at that moment.
Step 5: Therefore, at the moment the wheel is touching the ground, that point is momentarily at rest.
