Newton's Laws of Motion in Soccer By: Adiana lozada

Newton's 1st Law of Motion- As called Law of inertia, the object at rest stays at rest and an object in motion stays at motion with the same speed and same direction unless acted upon by an unbalanced force. v = final velocity, a = acceleration, t = time.

It is known that the object at rest stays at rest until an unbalanced force comes into contact. The soccer ball is at rest until the unbalanced force came upon it, the player's foot. The player's foot would be the unbalanced force that's acting upon the object that's in rest, the ball.

Newton's 2nd Law of Motion states “The change in velocity (acceleration) with which an object moves is directly proportional to the magnitude of the force applied to the object and inversely proportional to the mass of the object.” This can be explained in the equation F=ma.

F=ma; The acceleration of the ball would be (a) which is determined by the force applied (F) divided by the mass of the object that's being moved (m).

If the ball has a lot of mass, you would need more force to accelerate. If the ball has a little mass then you would need more force for it to accelerate. If you want the ball to be moving fast, you must apply more force. If you want the ball to move just a little bit, then you can just apply less force.

Newton's 3rd Law of Motion says that, For every action, there is an equal and opposite reaction. The statement means that 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.

If you would kick the soccer ball, it will kick back at you just as hard. You wouldn't be able to feel this because your leg has more mass, meaning it has more inertia, which is the resistance to move.

Momentum is mass in motion and only applies to objects in motion. It's a term that describes a relationship between the mass and velocity of an object, and we can see this when it is written in equation form, p = mv, where p is momentum, m is mass in kg and v is velocity in m/s.

When a soccer players kicks a ball, he transfers his momentum to the soccer ball. Momentum is the velocity of object times its mass. So when players pass the ball to each other, they use their feet to slow the momentum of the ball by moving with the ball and resisting it slowly. This way, they can have more control over the ball.
