dd = v₀t + ½gt² (Distance)
Overview
Free fall velocity is calculated using v = v₀ + gt, where velocity increases linearly with time. For objects starting from rest, velocity increases by approximately 9.81 m/s every second. This continues until terminal velocity is reached due to air resistance.

Pro Tips
Velocity increases linearly with time (constant acceleration).
Initial velocity (v₀) is zero for objects dropped from rest.
Final velocity tells you the speed just before impact.
In reality, air resistance limits velocity to terminal velocity (around 200 km/h for skydivers).
Velocity is a vector - downward velocity is positive in physics conventions.

Fun Facts
"The fastest recorded skydive speed is 373.6 mph (601 km/h) by Felix Baumgartner."
"A penny dropped from the Empire State Building reaches only about 65 mph."
"Terminal velocity for a skydiver in spread-eagle position is around 120 mph."
"The world record for fastest skydive in a tracking position is 843.6 km/h."
"Velocity increases by 32 ft/s² (9.8 m/s²) every second near Earth's surface."
