• Newton had an 'aha!' moment: Everything in the universe attracts everything else.
• If you've ever crushed on someone from afar, you know what gravity feels like. 😉
• Gravity's formula: F = \(\frac {g × m1× m2}{r^2}\)
• Where G is the universal flirty constant \(6.67 × 10^-11Nm_2 / kg^2.\)

• Gravity's like social media. The closer two people (or masses) are, the stronger their connection or gravitational force.
• Ever drop your ice cream on the ground? Earth's gravitational pull is why. It's like Earth saying, "Hey, give me some of that!"

Place a tiny 'test' object near a big one. The gravitational field strength is\(g = \frac {GM}{r^2} \)

• Imagine the sun (big object) and Earth (tiny one). Earth's drawn to the sun, like you to Netflix.

• Fancy name, simple idea. Double the distance? Quarter the force. It’s like if you shout at someone 2 times further away, they hear only a quarter of your scream.
• This isn’t just for gravity. Electricity plays by the same rules!

• Inertia = object's laziness to change motion.
• Gravitational mass = object's "likeability" by other masses.
• Einstein's brainwave: They’re the same!
• This idea, proven super accurate, was a cornerstone for his groundbreaking theories.
