Understanding Newton's Laws of Motion
Before diving into questions and answers, it’s essential to grasp the core concepts behind Newton's laws. These three laws, formulated by Sir Isaac Newton in the 17th century, form the foundation of classical mechanics and describe the relationship between the motion of an object and the forces acting upon it.
Newton's First Law: The Law of Inertia
- An object at rest stays at rest.
- An object in motion continues in motion with the same speed and direction unless acted upon by an external force.
Newton's Second Law: F = ma
- The force acting on an object is equal to the mass of the object multiplied by its acceleration.
- This law explains how the velocity of an object changes when it is subjected to an external force.
Newton's Third Law: Action and Reaction
- For every action, there is an equal and opposite reaction.
- This law describes the mutual forces of action and reaction between interacting bodies.
