Which of the following motions has a constant speed but changing velocity?
Which of the following motions has a constant speed but changing velocity?
medium Q7 of 15
Step-by-Step Solution
Step 1: Understand velocity and speed
Velocity is speed with direction. If direction changes, velocity changes even if speed is constant.Step 2: Analyze motion types
In rectilinear motion with uniform speed, velocity is constant. In circular motion with uniform speed, direction changes continuously, so velocity changes. Oscillatory and random motions have varying speeds.Final Answer:
Circular motion with uniform speed → Option BQuick Check:
Constant speed, changing velocity = circular motion ✅
Quick Trick: Uniform circular motion changes velocity due to direction change.
Common Mistakes:
MISTAKES- Assuming velocity is constant if speed is constant.
