1 Energy and Conservation Laws In this chapter, I experienced my first “aha!” moment. I never understood how police officers could determine the speed at which a car was traveling after a collision. I understood that math and physics were involved; however, I couldn’t put a name to the process. After reading chapter three, I discovered the phrase, conservation of linear momentum. The units involved in this concept include mass (kg) and velocity (m/s). The conservation of linear momentum law states that “the total linear momentum of an isolated system is constant” (Inquiry into Physics, p.85). To fully understand this statement, we can dissect it in more layman’s terms. In the statement, an “isolated system” indicates no outside force-producing change to a specific object. Instead, an object’s momentum can only change if another object in the same system interacts with that object. The example provided by the book is a cue ball hitting another ball on a pool table. Rockets and jet engines incorporate the conservation of linear momentum to produce enough velocity to keep the machines from stalling. Another example includes the process of firing a bullet from a gun. In the chamber, the bullets are at rest. Therefore, the velocity is zero. When the bullet is fired, multiple systems within the weapon enable the bullet to travel forward and the gun to kick back. These systems directly relate to the conservation of linear momentum. This law is extremely important today because when accidents occur on the roadways, a person is at fault most of the time. With the conservation of linear momentum law, the police can determine who is at fault and solidify the cause of the accident. Without this law, the police would have to question the people involved in the accident, and often there would be several different stories. This could be eliminated with the math and physics behind the conservation of linear momentum. Video The video attached helped me better understand the conservation of linear momentum law.
