This law explains why when you kick a soccer ball it goes flying and you feel the force on your foot in the opposite direction.
Newton's Third law of motion

What is Newton's First Law of Motion?
If an object is at rest it will stay at rest, if an object is in motion it will stay in motion until acted upon by an unbalanced force.
