1. Gravity is the natural force that attracts two objects with mass toward each other; on Earth, it’s what pulls things downward toward the ground.
2. Gravity is important to the universe because it holds celestial bodies together, shapes galaxies and solar systems, and governs the motion of planets, stars, and moons.
3. Gravity differs on each planet because it depends on the planet’s mass and radius; more massive planets exert stronger gravitational pull, while larger radius can reduce surface gravity.
4.
- Gravity keeps us grounded on Earth.
- It causes objects to fall when dropped.
- The Moon’s gravity causes ocean tides on Earth.
- Gravity holds the atmosphere around planets.
- All planets orbit the Sun due to its gravitational pull.
5. Without gravity, matter would not clump together to form stars or planets, orbits would not exist, galaxies wouldn’t hold shape, and everything would drift apart in space.
6.
- You could jump much higher and stay airborne longer.
- Objects would weigh far less, making them easier to lift.
- There would be no atmosphere retained, so no air to breathe.
7. Gravity pulls planets toward the Sun, while inertia keeps them moving forward in space; this balance results in stable orbits instead of falling into the Sun or flying off into space.
