How can I track third party conversion?

Identifying Newton's first, second, and third party motion laws. ?

• When the marble views over a hill on the track. When the marble goes around a turn on the track. When the marble goes through a flat portion of the track instead of down a down sloped portion of the track. Can you identify these with Newton's motion laws? An explanation would be greatly appreciated. Thanks!

• Answer:

  Assuming the a frictionless track (that still allows the marble to make a turn) Going downhill: This would be newtons second law, F=ma, the marble will accelerate from the force of earth's gravity Going around a bend: Also newtons second law, the marble is accelerating because its velocity is changing directions Flat portion of the track:Newtons first law, an object subject to no net force will experience no change in velocity. Also all three would have newtons third law, since the normal force and the weight of the marble will cancel out.
