When we measure the amount of gravitational pull on an object, we call that quantity (7)_____. This is different than an object's (8)_____, which is the amount of matter an object is made of.
Humans observe early on that things fall towards the earth when let go. This is due to the (4) law of universal gravitation, which states that the force of gravity acts between all objects in the universe. The scientist who discovered this was (5) Sir Isaac Newton. He described the force that pulls objects toward each other as (6) gravity. When we measure the amount of gravitational pull on an object, we call that quantity (7) weight. This is different than an object's (8) mass, which is the amount of matter an object is made of.

To understand this topic further, let's dive into each point in more detail:
4. The law of universal gravitation: This is a fundamental law of physics discovered by Isaac Newton. It states that every object in the universe attracts every other object with a force called gravity. The strength of this force is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between their centers. In simpler terms, all objects with mass exert a gravitational force on each other.
5. Isaac Newton: Isaac Newton was a renowned physicist and mathematician who made significant contributions to the field of physics, including the discovery of the law of universal gravitation. His work revolutionized our understanding of gravity and laid the foundation for classical mechanics.
6. Gravity: Gravity is the force that attracts objects with mass towards each other. It is responsible for the phenomenon of things falling towards the Earth when released. Gravity is an essential force in the universe, governing the motion of planets, stars, and other celestial bodies.
7. Weight: Weight is a measure of the gravitational force acting on an object. It is the force with which an object is pulled towards the center of the Earth (or any other massive body). Weight depends on both the mass of the object and the strength of the gravitational field it is in. Weight is typically measured in units of force, such as Newtons or pounds.
8. Mass: Mass is a fundamental property of an object that measures the amount of matter it contains. It is distinct from weight, as weight depends on the gravitational force acting on an object, whereas mass remains constant regardless of the gravitational field. Mass is typically measured in units such as kilograms or pounds. In simple terms, mass represents the quantity of matter in an object.
