Terminal velocity Flashcards
1
Q
what happens when you increase the speed of an object moving through a liquid
A
there is an increase of frictional force acting on the object
2
Q
why does an object initially fall through a liquid
A
due to gravity
3
Q
how is terminal velocity reached
A
eventually when the resultant force is 0
4
Q
how does the use of a parachute decrease the terminal velocity
A
because it creates air resistance
