Newton's Laws of Motion: Forces and Acceleration
Alison Francis
• Sir Isaac Newton's three laws of motion form the foundation of classical mechanics• These laws describe the relationship between forces and motion• Understanding these laws helps us predict and explain the behavior of objects in our world• Today, we'll explore each law and its applications in eNewton's First Law: The Law of Inertia• States that an object at rest stays at rest, and an object in motion stays in motion, unless acted upon by an external force• Key concept: Inertia - the resistance of any physical object to changes in its velocity• Examples:A book on a table remains statioNewton's Second Law: Force and Acceleration• Describes the relationship between force, mass, and acceleration• Mathematically expressed as: F=maF=maWhere:F = net forcem = mass of the objecta = acceleration• Key concept: The acceleration of an object is directly proportional to the net forceNewton's Third Law: Action and Reaction• States that for every action, there is an equal and opposite reaction• Key concepts:Forces always occur in pairsAction and reaction forces are equal in magnitude but opposite in directionThese forces act on different objects• Newton's Laws are fundamental to understanding motion and forces• They explain many everyday phenomena and have countless practical applicationsPause Answer these 3 questions on paper, you will submit your answers to today's dropbox on CTLSEmail me if you have any questions
