How Does Newton Present The Three Laws Of Motion

Sir Isaac Newton PRS was an English mathematician, astronomer, and physicist who is widely recognized as one of the most influential scientists of all time and a key figure in the scientific revolution. Newton made three different laws that each explain things about an object or a person with a force acting on it. Newton worked in many areas of mathematics and physics but developed the theories of physics in the year of 1666. Twenty years later in 1686, he presented the Three Laws of Motion in the "Principia Mathematica Philosophiae Naturalis." The three laws soon had a big impact on everyone and were to last throughout generations to come. Newton’s First Law explains how an object will stay at rest unless acted on by an unbalanced force. It also explains how an object in motion …show more content…

In order to stop a moving object, you must use a force to stop it. An example of this situation, can be wearing a seatbelt in the car to stop you when in a car wreck. The amount of momentum of an object is what will make it hard or easy to stop the moving object. Momentum depends on the velocity of an object and the mass of it. (Momentum = mass ✖ velocity). If there is an object going one way and a force acts on it going the same exact way, then it will accelerate. A large force will speed up an object more than a small force would because of the bigger impact. The longer the force is acting then the longer it will go, the shorter it acts then the shorter it will go. (Impulse = force ✖ time). If there is a car crash and the car suddenly stops, there would have needed to be a large force to stop it. Over half of all of the car crashes are like this. They head on into something making a rapid stop but to reduce the danger when this happens, car makers may weaken the front of the car so the crumple zone will extend the collision time, reducing the deceleration and the size of the forces
