Terminal Velocity
Initially the velocity of an object increases
as velocity increases, air resistance increases
until air resistance becomes equal to the weight of the object
so the resultant force is equal to 0 (forces are balanced/in equilibrium)
Describe how and explain between two points- not always explicitly says Terminal Velocity
X-Y: force A greater than force B, cyclist accelerates and velocity increases, as cyclist moves towards Y, force B increases (with increasing velocity) and resultant froce decreases, continues to accelerate to smaller value
Y-Z: air resistance increases acceleration decreases, force B is equal to force A, resultant force and acceleration is 0, cyclist travels at terminal velocity
