Newton's Laws

Newton's First Law of Motion (Law of Inertia)

An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
Inertia: the tendency of an object to resist changes in its motion.
Examples:
- A car maintaining its speed on a flat road.
- A ball continuing to roll on a frictionless surface.

Newton's Second Law of Motion (F = ma)

The force (F) applied to an object is equal to the mass (m) of the object multiplied by its acceleration (a).
F = ma
The more massive an object, the less it will accelerate when a given force is applied.
The greater the force applied, the greater the acceleration.

Newton's Third Law of Motion (Action and Reaction)

For every action, there is an equal and opposite reaction.
When two objects interact, they apply forces to one another that are equal in magnitude and opposite in direction.
Examples:
- When you push on a wall, the wall pushes back on you with equal force.
- When a car accelerates forward, the ground exerts an equal force backward on the car.

Test your understanding of Newton's three laws of motion, including the law of inertia, F = ma, and action and reaction. Apply your knowledge to examples of motion and forces.
