Sir Isaac Newton was born January 4th, 1643 was a great scientist. He is widely recognized for his discovery of gravity, but also for his three laws of motion. He died on March 31st, 1727, making remarkable discoveries before his death.
Newton's First Law of Motion
Newton's first law states that an object in motion will stay in motion, and an object in rest will stay in rest unless acted upon by an unbalanced force. Inertia can happen in a car when it is quickly braking to stop. The force of the road on the locked wheels gives the unbalanced force to the change the car's motion, but there is no unbalanced force to change your motion. You then continue sliding in a forward motion. A person in motion stays in motion with the same speed and direction unless acted upon an unbalanced force.
Newton's Second Law of Motion.
Newton's second law states that the acceleration of an object depends on the net force acting upon the object and the mass of the object. The husky is pulling a 50 kg rock with a net force of 100 newtons. Let's say the rock weighed 100 kg and the husky was only pulling with 50 N. The acceleration of the object would not nearly be as fast because the husky is pulling with a lesser force and the rock has more mass.
Newton's Third Law of Motion
Newton's third law of motion states that for every action there is an equal and opposite reaction. In this diagram, The action is the balloons air rushing downward and the opposite reaction is the balloon' movement upward. This balloon is creating two equal forces, one opposite the other.
