Pendulum in an Accelerating Elevator Quiz

What is the period of a pendulum attached to a stationary point?

• T = 2π√(L/G)

• T = L/2π√G

• T = G/2π√L

• T = 2π√(G/L)

How does the perceived gravity change for a person inside an accelerating elevator?

• It remains the same as 9.81 m/s²

• It decreases if the elevator accelerates upward

• It increases if the elevator accelerates upward

• It becomes zero

What is the modified period equation for a pendulum in an accelerating elevator?

• T = 2π√(L/(G+a))

• T = 2π√(L/(G-a))

• T = 2π√(G/L)

• T = 2π√(L/G)

Which forces act on a pendulum in an elevator?

• Only gravity

• Tension and gravity

• Only tension

• Friction and tension

What happens to the tension in the string when the elevator accelerates upward?

• It decreases

• It becomes zero

• It remains the same

• It increases

How does the restoring force affect the pendulum's motion in an accelerating elevator?

• It slows down the pendulum

• It stops the pendulum

• It speeds up the pendulum

• It has no effect

What is the effect of using a negative value for gravity in the period equation?

• It has no effect

• It doubles the period

• It results in an imaginary number

• It results in a correct period

Why should gravity be input as a positive value in the period equation?

• To make calculations easier

• To decrease the period

• To increase the period

• To avoid an imaginary number

What happens to the perceived gravity when the elevator accelerates downward?

• It becomes zero

• It increases

• It remains the same

• It decreases

What should be considered when determining the sign of 'a' in the modified period equation?

• The speed of the elevator

• The mass of the pendulum

• The length of the pendulum

• The direction of the elevator's acceleration
