Frictional force and terminal velocity

?
Friction is always there for?
slowing things down
1 of 13
If an object has no force propelling it along it will always slow down and stop because?
of friction
2 of 13
Friction always acts in?
the opposite direction to movement
3 of 13
To travel at a steady speed , the driving force needs to?
balance the frictional forces
4 of 13
You get friction between?
two surfaces in contact or when an object passes through a fluid
5 of 13
Most of the resistive forces are caused by?
air resistance or drag
6 of 13
The most important factor by far in reducing drag in fluids is ?
keeping the shape of the object streamlined
7 of 13
The opposite extreme is?
parachute which is about as high drag you can get
8 of 13
Drag increases as the ?
speed increases
9 of 13
Frictional forces from fluids always increase with?
speed
10 of 13
A car has much more friction to work when travelling at 70mph compared to?
30mph
11 of 13
So at 70mph the engine has to work much harder just to ?
maintain steady speed
12 of 13
Objects falling through fluids reach?
terminal velocity
