Universal Gravitation as One Explanation
Gravitation Newton Mass Attraction
0:18 Isaac Newton proposed a single principle to explain falling apples and orbiting moons, and the video addresses learners connecting terrestrial motion with celestial motion.
Gravity Strength Depends on Mass and Distance
Gravity Mass Distance Attraction
0:40 Any two objects with mass exert gravity on each other, and the video focuses on how that pull changes with size and separation.
Orbits as Sideways Falling
Orbits Velocity Gravity Moon
1:10 The video compares an apple thrown across Earth to the Moon circling Earth, showing how a single gravitational rule produces both falling and orbiting.
