Attwood lab - pre-lab video

What is the only "helping force" for an modified or traditional Atwood machine when looking at the whole system

• The force of gravity acting on the falling mass

• Both masses weight combined

• The falling mass

• The force of friction

When looking at the system as a whole, what mass contributes to the inertia (resistance to acceleration)

• The falling mass only

• the sliding mass only

• Both masses

• their total weight

For a modified atwood machine, what is the "hurting force" for the system as a whole?

• The weight of the falling mass

• The weight of the sliding mass

• The normal force

• The friction acting on the sliding mass

If we just looked at the sliding mass, what is the helping force?

• The friction

• The normal force

• The tension

• The weight of the sliding mass

IF we just look at the falling mass, what is the "hurting force"

• The falling masses weight

• The tension pulling it up

• The force of friction of the sliding mass

• The sliding masses weight

Once you know the systems acceleration, what system can you then look at to determine the tension in the rope

• The big system with both block in it

• Only the falling mass system

• Only the sliding mass system

• Either the sliding mass or the falling mas
