Understanding the Funicular Experiment

Tadashi demonstrates a funicular using a binder clip and string, explaining how symmetric up-and-down motions can cause upward movement due to friction differences. The device's function is influenced by focus and threading, with static and dynamic friction playing key roles.

What is the initial setup described for the funicular experiment?

• A piece of blue string and a paper clip

• A piece of red string and a binder clip

• A piece of green string and a safety pin

• A piece of yellow string and a clothespin

What is the main challenge in moving the passenger up the mountain?

• Using a longer string

• Keeping the strings parallel

• Increasing the weight of the passenger

• Decreasing the height of the mountain

What is the significance of keeping the strings parallel?

• It has no significance

• It makes the clip move faster

• It prevents the clip from moving

• It ensures the clip moves in a straight line

How does the clip move upwards despite the symmetric motion?

• Due to the wind pushing it upwards

• Due to the alternating tugging of strings

• By increasing the weight of the clip

• By using a motor

What happens when the person is distracted while performing the experiment?

• The clip stops moving

• The clip moves downwards

• The clip moves sideways

• The clip moves faster

What is the role of static friction in the experiment?

• It prevents the clip from moving

• It helps the clip move downwards

• It helps the clip move upwards

• It has no effect on the clip

What is the difference between static and dynamic friction in this context?

• Both frictions are equal

• Static friction is weaker than dynamic friction

• Dynamic friction is stronger than static friction

• Static friction is stronger than dynamic friction

How does the threading of the string affect the direction of the clip's motion?

• It makes the clip move in circles

• It has no effect on the clip's motion

• It makes the clip move faster

• It determines whether the clip moves up or down

What happens when the binder clip is turned around?

• The clip moves downwards

• The clip moves sideways

• The clip stops moving

• The clip moves upwards

What is the main takeaway from the experiment?

• The importance of using a longer string

• The role of color in the experiment

• The effect of threading on motion direction

• The need for a heavier passenger
