Which of the following best describes the motion of a bob in a simple pendulum?
hard Q10 of 15
Step-by-Step Solution
Step 1: Understand pendulum motion
A simple pendulum swings back and forth about a mean position repeatedly.Step 2: Identify motion types
This back and forth repeated motion is oscillatory and periodic. It is not circular because the path is an arc, not a full circle. It is not random or rectilinear.Step 3: Analyze incorrect options
Random and rectilinear motion do not describe pendulum motion. Circular motion implies full rotation, which pendulum does not perform. Uniform rectilinear motion is straight line at constant speed, which is not the case.Final Answer:
Periodic and oscillatory motion → Option AQuick Check:
Pendulum motion = periodic and oscillatory ✅
Quick Trick: Pendulum swings back and forth periodically.
Common Mistakes:
MISTAKES- Confusing pendulum motion with circular or random motion.
