Which of the following motions involves acceleration even if speed remains constant?
Which of the following motions involves acceleration even if speed remains constant?
hard Q9 of 15
Step-by-Step Solution
Step 1: Understand acceleration
Acceleration is the rate of change of velocity, which includes changes in speed or direction.Step 2: Analyze uniform circular motion
In uniform circular motion, speed is constant but direction changes continuously, causing centripetal acceleration.Step 3: Analyze other options
Uniform rectilinear motion has constant velocity, so no acceleration. Oscillatory motion at rest means no motion. Random motion with variable speed has acceleration but speed is not constant.Final Answer:
Uniform circular motion → Option CQuick Check:
Acceleration with constant speed = uniform circular motion ✅
Quick Trick: Change in direction causes acceleration even if speed is constant.
Common Mistakes:
MISTAKES- Ignoring acceleration due to direction change in circular motion.
