Free Fall
Also known as: falling, gravitational acceleration
Motion under the influence of gravity alone, with no air resistance acting on the object. Fundamental to understanding projectile motion, orbits, and gravitational acceleration.
💡 Intuition
A dropped ball accelerates at the same rate regardless of its mass.
Core Idea
Gravity gives the same acceleration to all objects in a vacuum, regardless of mass.
🔬 Example
🎯 Why It Matters
Fundamental to understanding projectile motion, orbits, and gravitational acceleration.
⚠️ Common Confusion
Heavier objects fall at the same rate as lighter ones (ignoring air).
