Uniform acceleration and falling
Uniform acceleration and fallingFree7:07Heddy Score 3 of 7, below the standard
What you need to know
- A falling object's weight stays the same, and at first it is the only force, so the object speeds up.
- Air resistance comes from collisions with air particles and grows as the object falls faster.
- As air resistance grows, the resultant force and the acceleration both get smaller.
- When air resistance equals weight, the resultant force is zero and the object falls at terminal velocity.
- Opening a parachute increases air resistance, so the skydiver slows to a new, lower terminal velocity.
