Sir Isaac Newton was an English mathematician and physicist who is best known for developing the three laws of motion. His first law is often referred to as the "Law of Inertia”. It states that an object at rest will remain at rest unless acted on by an unbalanced force. Additionally, an object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This means that objects naturally keep on doing what they 're doing and resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain this state of motion. His second and most powerful law says that the relationship between an object 's mass m, its acceleration a, and the applied force F, is F = ma. This means acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force needed to accelerate the object. Therefore, heavier objects require more force to move the same distance as lighter objects. His third and final law is for every action there is an equal and opposite reaction. This means that for every force there is a reaction force that is equal in size, but opposite in direction. Therefore, whenever an object pushes another object, it gets pushed back in the opposite direction equally hard.
Continuing, the stopping distance is the distance it takes your car to stop. It is made up of the reaction distance plus the braking distance. Reaction distance is the distance the car…
