Newton's Laws of Motion
By: Kelsie C.

    Newton’s first law of motion states that an object will not change its motion unless a force acts on it, an object that is not moving remains at rest until something pushes or pulls it, an object that is moving remains moving until something pushes or pulls it, all objects resist having their motion changed; this is called inertia, and the more mass an object has, the greater its inertia. Or in other words Newton’s first law of motion says 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. Or in other words Newton’s first law of motion says 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.

 The second law of motion states 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, a net force changes the velocity of the object, and causes it to accelerate, if an object is acted upon by a net force, the change in velocity will be in the direction of the net force, the acceleration of an object depends on its mass, the more mass an object has or the more inertia it has, the harder it is to accelerate, the more mass means less acceleration if the force acting on the objects is the same.

Finally, Newton’s third law of motion states that when one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object, the force exerted by the first object is the action force, and the force exerted by the second object is the reaction force. In other words, Newton’s third law of motion states that for every action there is an equal and opposite reaction.
