Law's of Motion ✅🎯

Описание: Newton's Three Laws of Motion describe the relationship between an object and the forces acting on it: the First Law (Inertia) states objects resist changes in motion; the Second Law (\(F=ma\)) links force, mass, and acceleration; and the Third Law (Action-Reaction) says every action has an equal and opposite reaction, forming the foundation of classical mechanics. 1. First Law (Law of Inertia) Definition: An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction, unless acted upon by an unbalanced external force.Concept: This law defines inertia, the tendency of an object to resist changes in its state of motion, and defines force as what causes these changes.Example: A soccer ball sits still until kicked (force applied); once rolling, it continues until friction or a player stops it. 2. Second Law (Force and Acceleration) Definition: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.Formula: \(F=ma\) (Force = mass × acceleration).Concept: A larger force produces greater acceleration; a more massive object requires more force to accelerate at the same rate.Example: Pushing a light shopping cart is easy, but pushing a heavy one (more mass) requires much more force to get it going. 3. Third Law (Action-Reaction) Definition: For every action, there is an equal and opposite reaction.Concept: Forces always occur in pairs; when one object exerts a force on a second object, the second object simultaneously exerts a force equal in magnitude and opposite in direction on the first.Example: When you push on a wall (action), the wall pushes back on you with the same force (reaction). These laws, published by Isaac Newton in 1687, are fundamental to understanding classical physics and how objects move in our everyday world.
