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

  1. First Law (Inertia): Objects stay at rest or in motion unless acted on by a force.
  2. Second Law: Force equals mass times acceleration (\( F = ma \)).
  3. 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.

Key Terms

Force
A push or pull that can change motion.
Gravity
A force that pulls objects toward each other.
Friction
A force that resists motion between two surfaces.
