Newton's First Law of Motion | Newton's first law of motion states that an object at rest will remain at rest unless an unbalanced force is acted upon it. Also, an object in motion will remain in motion unless an unbalanced force is acted upon it |
Newtion's Second Law of Motion | Newton's second law of motion states that the accleleration of an object depends on the objects mass and the size of the force applied to it |
Newton's Third Law of Motion | Newton's Third law of motion states that for every action, there is an equal and opposite reaction |
Unbalanced force | An unbalanced force is a force that is applied to an object and causes that object to move |
Balanced Force | A balanced force is a force applied to an object that causes no movement. (forces are equal) |
