What is the effect called when a pendulum swings in a way that each swing takes the same amount of time?

• A. Simple harmonic motion
• B. Exponential decay
• C. Circular motion
• D. Linear motion

Answer: (A)

The phenomenon described is known as simple harmonic motion. This type of motion occurs when an object oscillates back and forth around a central equilibrium position, and the time taken for each complete cycle (or swing in the case of a pendulum) remains constant regardless of the amplitude of the oscillation. In simple harmonic motion, the restoring force acting on the pendulum is directly proportional to the displacement from its equilibrium position, which allows the pendulum to swing with a consistent period. This characteristic leads to the predictable time intervals between swings, which is a fundamental aspect of simple harmonic motion and distinguishes it from other types of motion. The other options do not pertain to the consistent timing of swings characteristic of a pendulum. Exponential decay refers to processes where quantities decrease at rates proportional to their current values, circular motion involves movement along a circular path, and linear motion pertains to movement in a straight line. Each of these does not exhibit the repeatable time characteristics associated with the swings of a pendulum moving in simple harmonic motion.
