Newton's Laws of Motion

Isaac Newton was born on January 4, 1643 in Woolsthorpe-by-Colsterworth, United Kingdom. He was born premature and was not expected to survive, but surely enough he did. Therefore, he was an English physicist and mathematician and most famously known for his laws of gravity. In his final years, he was one of the most famous men in Europe. He died on March 31, 1727, at the age of 85.
Newton's first law of motion is that an object in motion will stay in motion and an object at rest will stay at rest unless acted on by an unbalanced force.
- An object will not change its motion unless a force acts on it.
- All objects resist having their motion changed.
- The more mass the objects has, the greater its inertia!
Newton's second law of motion is that the force of an object is equal to its mass times its acceleration.
- A change in motion occurs only if a net force is exerted on an object.
- The acceleration of an object depends on its mass.
- The more mass an objects has or the more inertia, the harder it is to accelerate.
Newton's third law of motion is that for every action there is an equal and opposite reaction.
- The force exerted by the first object is the action force.
- The force exerted by the second object is the reaction force.
