Questions & Step-by-Step Solutions

In a stable rolling motion, what is the relationship between the center of mass and the base of the object?
  • Step 1: Understand what the center of mass is. It is the point where the mass of the object is balanced.
  • Step 2: Identify what the base of the object is. It is the part of the object that is in contact with the ground.
  • Step 3: Recognize that for an object to roll without tipping over, it needs to be stable.
  • Step 4: Know that stability in rolling motion means the center of mass should be directly above the base.
  • Step 5: Conclude that if the center of mass is above the base, the object will not tip over and can roll smoothly.
  • Center of Mass and Stability – The center of mass must be positioned above the base of the object to maintain stability during rolling motion.
