# application newtons law of inertia

From Wikipedia

Newton's laws of motion

Newton's laws of motion consist of three physical law s that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries, and can

Question:I am doing a science project . Is a girl riding a surf board considered to be Newtons first law of motion ? I have a science Project and isnt a girl riding a surfboard considered to be Newtons first law? & Newtons First law, isnt it An object will stay at rest unless another object will act upon it???

Answers:Theoretically, this is a scenario where the three Laws Of Newton can be applicable. Anyway, Newton's 1st Law is also known as the Law of Inertia and fora science project, I would suggest a very simple demonstration like so. Place a block (or any object) on a smooth table. Note that this block is not moving initially. If you apply an external force on it (in other words, push or pull it), the block will obviously move consistent with the direction of the applied force. If the external force is taken off (i.e., you stop pushing or pulling), the block will simply stop. Another way the block will stop is when something stops it from moving. It could be an impediment or simply anything that will prevent the block from moving. Hope this helps.

Question:

Answers:First off, every action has an equal and opposite reaction. If you look at a helicopter, the blade on top spins, and it needs the blade rotating in the back to keep the cabin from spinning like crazy. Then second, inertia, a plane takes off to a high altitude, then it only needs to produce enough thrust to overcome air resistance to maintain speed, inertia does the rest.
