Drag

Question 1

Describe what happens as a ball bearing as it is falling through glycerol

Answer 1

the drag from the fluid increases with velocity. The falling object accelerates at first, but them reaches terminal velocity when drag has become equal to weight.

Question 2

Name 3 things drag is affected by

Answer 2

1) Velocity
2) Air density
3) Shape and size of the object

Question 3

What would a graph look like for terminal velocity?

Answer 3

Would be terminal velocity against time and it would be a curve levelling off to represent terminal velocity

Question 4

Describe an experiment to measure terminal velocity using a ball bearing

Answer 4

A stopwatch is used to time its fall through a measured distance
