Air resistance makes it harder to understand how objects fall freely.

1. Challenge:

   • When things fall, they don’t speed up the same way because of forces pushing against them.
   • The shape, size, and speed of an object can cause different and unexpected outcomes.

2. Consequences:

   • When objects fall in the air, they don't show exactly how gravity works (about 9.81 m/s²).
   • Different objects fall at different speeds when they reach their highest fall speed, known as terminal velocity.

3. Solution:

   • Using advanced computer models and experiments can help us understand these things better, showing us how free fall really works.
