Basic Concepts
In a nutshell: Newton’s Laws explain how forces affect the motion of objects.
## The Rules That Govern Motion
Newton's three laws describe the relationship between forces and motion, forming the foundation of classical mechanics.
### The Laws
1. **First Law (Inertia):** Objects remain at rest or move at a constant speed unless acted on by a net force.
2. **Second Law (F=ma):** The acceleration of an object depends on its mass and the net force applied.
3. **Third Law (Action-Reaction):** Every action has an equal and opposite reaction.
### Applications
These laws explain everything from why you lurch forward in a stopping car to how rockets launch into space.
### Everyday Physics
Whether you're pushing a friend on a swing or watching a skateboarder perform tricks, Newton's laws are at work.
Examples
- A skateboarder pushes off the ground and accelerates forward.
- When you jump off a boat, the boat moves backward.
