Velocity and acceleration Practice Questions

Question 1 of 1 NDA MCQ

At uniform speed the acceleration is

Detailed Explanation

✓

Option C is correct. At uniform speed, the acceleration is zero.

At uniform speed, an object maintains a constant velocity, resulting in no change in speed or direction, and hence, acceleration is zero.

Acceleration \((a)\) is defined as the change in velocity \((\Delta v)\) over time \((\Delta t)\):

\[ a = \frac{\Delta v}{\Delta t} \]

For uniform speed, \(\Delta v = 0\):

\[ a = \frac{0}{\Delta t} = 0 \]

Hence, the acceleration is zero.

•Option A: Maximum acceleration is not applicable since there is no change in velocity.
•Option B: Minimum does not pertain to a static zero value in motion.
•Option D: Constant acceleration indicates a change in speed, contradicting uniform speed.

⚡

Remember: Uniform motion = constant velocity, hence acceleration = 0.

🎯

At uniform speed, acceleration is always zero.
