🌍 Gravity
Learn gravity with animated falling objects, Earth’s pull, orbit demonstration, weight calculator, real-life examples, quiz, HOTS and FAQ schema.
📌 What is Gravity?
Gravity is a force that pulls objects toward each other. On Earth, gravity pulls objects downward toward the centre of the Earth.
🌍 Earth’s Pull
Earth pulls all objects toward its centre.
Example: A ball falls down after being thrown upward.🍎 Falling Objects
Objects fall because gravity pulls them downward.
Example: An apple falls from a tree.⚖️ Weight
Weight is the force of gravity acting on mass.
Formula: Weight = Mass × Gravity.🌈 5W-1H + 1U
🔴 What: Gravity is the force of attraction between objects.
🟠 Why: Gravity keeps us on Earth and makes objects fall downward.
🟡 When: Gravity acts all the time between objects that have mass.
🟢 Where: Gravity acts on Earth, in space and throughout the universe.
🔵 Who: All objects with mass experience gravity.
🟣 How: Gravity pulls objects toward each other.
⚫ 1U: Gravity keeps the Moon in orbit around Earth and planets in orbit around the Sun.

Gravity Pulls Objects Downward

The apple falls because Earth’s gravity pulls it downward toward the centre of the Earth.
Weight = Mass × Gravitational Acceleration
W = m × g
On Earth, g is approximately 9.8 m/s².
🌙 Gravity and Orbits
Animated Moon Orbit
🌍
🌙
The Moon stays in orbit because Earth’s gravity pulls it inward while the Moon keeps moving forward.
Why Moon Does Not Fall Straight Down
The Moon moves forward while Earth pulls it inward, creating an orbit.
Why Planets Orbit the Sun
The Sun’s gravity pulls planets inward while they continue moving forward.
Why We Stay on Earth
Earth’s gravity pulls our bodies toward the ground.
🧮 Weight Calculator
Calculate Weight on Earth
Compare Earth and Moon Weight
Mass remains the same everywhere, but weight changes because gravity changes from place to place.
✅ Gravity Quiz
🧠 HOTS Questions
1. Why does an apple fall downward?
It falls because Earth’s gravity pulls it toward the centre of Earth.
2. Why does the Moon not fly away?
Earth’s gravity pulls the Moon inward and keeps it in orbit.
3. Why is weight less on the Moon?
The Moon has weaker gravity than Earth, so the force of gravity on the same mass is less.
4. Can gravity act in space?
Yes. Gravity acts in space and keeps planets, moons and satellites in orbit.
5. Why does mass not change from Earth to Moon?
Mass is the amount of matter in an object, and that amount does not change when the object moves to the Moon.
