Rock 'n Roller Coaster and Newton's LawsNick whitaker
Newton's First Law. Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The roller coaster starts only when pressured by an outside force.
The second law states that F=ma, or force is equal to mass times acceleration. When the roller coaster is going down its first big downhill drop, the acceleration due to gravity is acting on it in a downward manner thus giving a downward force to the coaster.
Gravity is what makes roller coasters fun, gravity also has a direct effect on speed and acceleration.This laws also applies because the more mass on the roller coaster, the more force it will take the roller coaster to make the cars accelerate at the same rate as an empty car
