A marble would roll around in a pie plate in a circular path until it reaches the part where a section is cut out. At that section the marble would: A) roll in a straight path at a constant speed from the edge of the pie plate or B) continue to roll in a circle around the pie plate. Pick what the marble will do and tell why.
What is roll in a straight path at a constant speed from the edge of the pie plate because of Newton's First Law of Motion?
