Newton's Laws of Motion

Class Response- Science

3 interesting facts:
1.) There are three laws of motion
2.) The first law of motion states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force.
The second law of motion states that force is mass times acceleration.
The third law of motion states that for every action there an equal and an opposite reaction.
3.) Friction brings an object to rest

2 facts learned from another source:
1.) Newtons second law is the most important of the three because it explains how velocities change when force is applied.
2.) The First law of motion was recognized as Galileo's concept of inertia.

My Opinion:
I think that Newton's laws are extremely important because they help us understand the concept of what happens when motion and force and friction are all applied.  We need to know this because if we become engineers we need to know about friction and force.  Also, this information was very helpful and the basis of being able to build our roller coasters.
