Understanding Torque and Force Vectors

What happens when you pull the string at a slight upward angle?

• The spool spins in place.

• The spool does not move.

• The spool moves to the left.

• The spool moves to the right.

What is the main concept that explains the rotation of the spool?

• Gravity

• Friction

• Torque and force vectors

• Inertia

What is the effect of pulling the string horizontally?

• It produces no torque.

• It produces a clockwise torque.

• It produces a counterclockwise torque.

• It causes the spool to lift off the ground.

Where is the pivot point of the spool as it rolls?

• At the center of the spool

• At the top of the spool

• Where the spool touches the ground

• At the end of the string

What happens when the force vector passes through the point of contact with the ground?

• The spool moves to the left.

• The spool moves to the right.

• The spool spins in place.

• The spool does not move.
