1
Q
what is terminal velocity
A
the fastest speed that an object can reach when falling
2
Q
when is terminal velocity reached
A
when the upward and downward acting forces are balanced, so there is no resultant force, meaning no acceleration so velocity is constant
3
Q
Falling objects experience two forces:
A
weight and air resistance
4
Q
The force of air resistance increases as
A
the objects speed increases
