Class Response 1 (Trimester 3)

The most recent topic that came to mind when reminded of a class response due on
May 11th were Newtons laws,his laws changed our concept of the universe.
Law 1 "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it", this can also be called the law of Inertia.
Law 2 "The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.", this states how mass and velocity are directly related, an object will change velocity if pushed or pulled upon.
Law 3 "For every action there is an equal and opposite reaction." For example on a boat if you want to get off it u have to push backwards to go forwards.
Without these laws, the understanding of the universe wouldn't be so clear to us now, these laws help define our everyday motions and without it we would be pretty much clueless of the world of motion and physics.
