## Newton's 3 Laws of MotionBy: Natalia ollio

Newton's 1st Law of Motion: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Soccer example: A soccer ball will not move until a player kicks it. The soccer player's foot is the unbalanced force because only his/her force will move the ball.

Newton's 2nd Law of Motion: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Soccer Example: If the ball’s mass is high, it will require more force to accelerate. If the ball’s mass is low, it will require little force.

Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction. In every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Soccer Example: If you kick the soccer ball, it will kick back at you just as hard. The reason the ball moves is because your leg is exerting a higher amount of force opposed to the soccer ball.
