Q: What is Newton’s Third Law of Motion? A: Newton’s Third Law of Motion: Action and Reaction Explained Newton’s Third Law of Motion is one of the simplest yet most powerful principles in physics. It states: For every action, there is an equal and opposite reaction. In other words, forces always come in pairs. If … Read more
Q: What is Newton’s Second Law of Motion? A: Newton’s Second Law states that the force acting on an object is equal to its mass multiplied by its acceleration (F = ma), where F is force, m is mass, and a is acceleration. Did you know? Newton’s Second Law (F = ma) explains why it’s … Read more
Q: What is Newton’s First Law of Motion? A: Newton’s First Law states that an object will remain at rest, or continue to move in a straight line at constant speed, unless acted upon by an external force. Did you know? It is Newton’s First Law that explains why passengers lurch forward in a car … Read more
