Physics: Forces and Motion
The Rules That Move the World
Physics explains how and why things move. Forces are pushes or pulls that can change an object's motion.
Newton's Laws of Motion
- First Law (Inertia): Objects stay at rest or in motion unless acted on by a force.
- Second Law: Force equals mass times acceleration (\( F = ma \)).
- Third Law: For every action, there is an equal and opposite reaction.
Everyday Forces
Gravity keeps us on Earth, friction slows things down, and applied forces make things move.
Real-World Connections
Understanding forces helps us build safer cars, design roller coasters, and even play sports better!
Formula
"F = ma"
Key Formula
\[F = ma\]
Examples
Kicking a soccer ball applies a force that makes it move.
A car stops quickly because of friction between the tires and the road.
In a Nutshell
Forces cause motion and are described by Newton's laws.
