Newton's Three Laws of Motion are fundamental principles that describe the relationship between the motion of an object and the forces acting upon it. Here are the laws:
### 1. Newton's First Law of Motion (Law of Inertia):
An object at rest remains at rest, and an object in motion continues to move at a constant velocity in a straight line unless acted upon by a net external force. This law implies that if no net force acts on an object, its state of motion will not change.
### 2. Newton's Second Law of Motion (Law of Acceleration):
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be summarized by the equation:
\[ F = ma \]
where:
- \( F \) is the net force acting on the object (measured in newtons),
- \( m \) is the mass of the object (measured in kilograms),
- \( a \) is the acceleration of the object (measured in meters per second squared).
### 3. Newton's Third Law of Motion (Action and Reaction):
For every action, there is an equal and opposite reaction. This means that for every force exerted by one object on another, there is a force of equal magnitude but opposite direction exerted by the second object back on the first.
These laws form the foundation for classical mechanics and are essential for understanding the motion of objects in various contexts, from everyday situations to complex engineering applications.
