This lesson focuses on Newton's First Law: an object remains in the same state of motion unless a resultant force acts on it. If the resultant force on an object is zero, this means: a stationary object stays stationary; a moving object continues to move at the same velocity (at the same speed and in the same direction). Links to a video and a test are provided.
