PHYSICS GROUP LAB EXAM REVIEW I

Work in a group of 2-3 ..... and
keep careful notes.

THE PROBLEM:

To
roll a ball off a ramp then off a table so that it reaches the ground in
exactly 2 seconds and be able to mark where it lands. NOT TRIAL AND ERROR!

Friction
and air resistance are NOT in effect.

I) What would the path, and the
distance-time, velocity-time, and acceleration-time graphs look like?

II) How would you set up the
problem. What measurements would you need to take, how would you do it, and
what results would you predict? Try and have the __least__ number of
measurements possible. Show a data table and picture of your setup.

III) What calculations would you
do to calculate the “answer”?

PHYSICS GROUP LAB EXAM REVIEW II

Work in a group of 2-3... keep
careful notes:

THE PROBLEM:

To
slide coffee filter(s) off a table so that it reaches the ground in 2 seconds,
and be able to mark where it lands. NOT TRIAL AND ERROR!

Friction,
AND air resistance are in effect.

In
this case the FORCE of air resistance is proportional to the instantaneous
VELOCITY of the object... it increases as velocity increases, and decreases as
velocty decreases. This means that there is almost a constant change in
acceleration (JERK) till A is zero.

I) What would the path, and the
distance-time, velocity-time, and acceleration-time graph look like for NO friction, air resistance? How about
with?

II) How would you set up an
experiment to find out what other factors the force of air resistance depends
on? What measurements would you need to take, how would you do it, and what
results would you predict? Show a data table and picture of your setup.

III) What calculations would you
do to calculate the “answer”?
