This study guide covers Newton's Second Law, focusing on its formula (F=ma), the relationship between force, mass, and acceleration, and how unbalanced forces cause acceleration. It explains net external force and its impact on velocity changes. The guide also provides practice questions (multiple-choice and free-response) and exam tips emphasizing free-body diagrams and problem-solving strategies.
