This section explores Galileo's experiments on motion and introduces Newton's First Law of Motion.
Galileo's Observations:
Example: On a downward slope, a ball picks up speed due to gravity. On an upward slope, it slows down as it moves against gravity.
Introduction to Inertia: Galileo proposed that it's natural for a moving body to keep moving, and every material resists changes to its state of motion.
Definition: Inertia is the property of a body to resist changes in its state of motion.
Newton's First Law of Motion - The Law of Inertia:
Quote: "Every object continues in a state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by the forces exerted upon it."
Highlight: In a force-free environment, an object will move indefinitely. A force is needed to overcome friction and set objects in motion.

This section discusses the concept of mass and its relationship to inertia and force.
Mass and Inertia:
Definition: Mass is the quantity of matter in an object and a measure of its "laziness" in response to efforts to change its state of motion.
Distinguishing Mass, Volume, and Weight:
Net Force: The combination of all forces acting on an object is called the net force.
Highlight: Net force changes an object's state of motion. In the absence of a net force, objects maintain their current state of motion (rest or constant velocity).

This final section covers equilibrium conditions, vector properties of forces, and revisits the concept of Earth's motion.
Equilibrium:
Example: When hanging from a rope, you are in equilibrium if the tension in the rope equals your weight.
Forces as Vectors:
Earth's Motion:
Highlight: Aristotle's view of horizontal motion as "unnatural" was incorrect. Galileo and Newton showed that all moving objects follow the same rules of motion.
This chapter provides a comprehensive overview of the historical development of motion theories and introduces fundamental concepts in physics, setting the stage for a deeper understanding of mechanics and dynamics.

This page examines the concept of equilibrium and vector forces, explaining how objects remain stable under various force conditions.
Definition: Equilibrium occurs when the net force on an object equals zero.
Example: A hanging object is in equilibrium when rope tension equals its weight.
Highlight: The Earth moves at 30 km/s, yet objects maintain their relative positions due to inertia.
Vocabulary: Vector quantities have both magnitude and direction.

This section introduces Aristotle's theories on motion and contrasts them with later scientific developments.
Aristotle's Theory of Motion: Aristotle, the Greek scientist, proposed two types of motion:
Definition: Natural motion is the inherent tendency of objects to move in straight lines or circles without external forces.
Definition: Violent motion, also called "imposed motion," results from external forces pushing or pulling an object.
Aristotle's view on Earth's position:
Copernicus and the Heliocentric Model:
Galileo's Support for Copernicus: Galileo agreed with Copernicus's heliocentric model, challenging the prevailing Earth-centered view.
Vocabulary: Force is any push or pull that can cause an object to move.
Vocabulary: Friction is the force that acts between materials that touch as they move past each other, caused by surface irregularities.
