1. What is the center of oscillation in a compound pendulum?
The point where, if the entire mass were concentrated, the time period would remain unchanged
The point at which a pendulum stops oscillating
The point where the entire weight of the pendulum acts
The point where the pendulum is suspended from
2. What defines the center of percussion of a pendulum?
The point at which the pendulum is suspended
The point where an impact causes maximum force at the pivot
The point of maximum oscillation
The point where an impact does not cause a reactive force at the pivot
3. What is the center of suspension in a pendulum?
The point of maximum amplitude
The point of equilibrium in oscillatory motion
The point where the pendulum's mass is concentrated
The point where the pendulum is hung and oscillates about
4. What is the center of mass of a body?
The point where the entire mass can be considered concentrated for translational motion
The point from which the pendulum hangs
The point where all gravitational forces cancel out
The geometric center of the object
5. How is the center of gravity best defined?
The point where the gravitational field is strongest
The point at which the entire weight of the body acts for analyzing gravitational effects
The point where net torque is zero
The same as the center of oscillation
6. Which of the following statements best explains why Kater's Pendulum is considered better than a Bar Pendulum for measuring gravity?
Kater's Pendulum eliminates the effects of air resistance and friction through knife-edge suspension and reversibility, leading to more accurate measurements.
Kater's Pendulum is shorter and lighter than a Bar Pendulum, making it easier to handle.
Bar Pendulum is more accurate because it has fewer components.
Kater's Pendulum is better because it is simpler to construct and use.
7. What defines a simple pendulum?
A heavy particle suspended from a fixed support by a light inextensible string
A rigid body oscillating about a horizontal axis
A system of pendulums of varying lengths connected to a bar
A pendulum with mass distributed along its length
8. Which of the following best describes a compound pendulum?
A set of pendulums transferring energy to each other
A mass on a string swinging in a circular path
A particle suspended from a light string
A rigid body oscillating about a horizontal axis in a vertical plane
9. What distinguishes a compound pendulum from a simple pendulum?
It oscillates in a horizontal rather than a vertical plane
It uses a spring instead of a string
It swings faster than a simple pendulum
It has mass distributed along its length and a moment of inertia
10. What is Barton’s Pendulum known for?
Its oscillation in a conical path
Having multiple pendulums of varying lengths transferring energy through a common bar
Being a rigid body with a fixed pivot point
Using a spring for its motion
11. What describes a conical pendulum?
A pendulum that oscillates in a straight line
A mass on a string that swings in horizontal circles, tracing a cone
A heavy particle on a rigid rod swinging back and forth
A pendulum system used to transfer energy among multiple masses
12. What is the principle of a bar pendulum?
It oscillates under the influence of restoring torque due to elasticity
It works on the principle of electromagnetic induction
It behaves like a compound pendulum and follows the laws of simple harmonic motion under gravity
