Chapter 5: Newton's Laws of Motion 
1. Newton's First Law: An object will remain at rest or move in a straight line at constant speed 
unless acted upon by a net external force (law of inertia). 
2. Newton's Second Law: The acceleration of an object is directly proportional to the net force 
acting on it and inversely proportional to its mass (F = ma). 
3. Newton's Third Law: For every action, there is an equal and opposite reaction. 
4. Applications: Problems involving friction, tension, an...
