5. What made Isaac Newton think about why apples fall?Newton saw an apple fall from a tree and wondered why it moved toward the ground. This curiosity led him to study the force that pulls objects together.
6. How did Newton explain the motion of planets?He wrote that every particle pulls on every other particle, and the pull depends on their masses and how far apart they are. This idea explains why planets orbit the Sun.

Laws of Motion: Three fundamental principles describing the relationship between an object's motion and the forces acting upon it.
Universal Gravitation: The principle that all objects with mass attract each other with a force dependent on their masses and distance.
Calculus: A branch of mathematics concerned with rates of change and accumulation, essential for analyzing dynamic systems.
Reflecting Telescope: A telescope that uses mirrors to gather and focus light, offering advantages over early refracting designs.
