Newtons Laws of Motion 


An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Otherwise known as Newtons First Law, "the law of inertia"

This Law, basically states that an object has the tendency to continue doing what they are doing until acted upon by another force. In a place where all forms of restriction are absent. the object will remain in motion forever. 
  • For example,when a ball is rolled on a floor, it eventually comes to a stop because of the opposite force of friction. With the absence of friction, the ball would continue to roll because there is not force stopping it from gaining ground. 
Newtons Second Law of Motion

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

This law states that an object carrying a greater mass will take a greater amount of energy or newtons to move than an object with a smaller mass.
  • To prove this theory, Newton created an equation that supports his claim. The equation is F = M x A, or Force equals mass times acceleration. When u plug in certain values for M, it is clear than the F will be higher if the mass is greater. 
Newtons Third Law of Motion 

For every action there is an equal and opposite re-action.



This Law states that for every force acted upon an object, there is an equal reaction force in the opposite direction. 

  • For example, when a person drives into a wall with 560 newtons of force, the wall gives back 560 newtons of force in the opposite direction, crushing the car.
