Which one of the following equations related to the motion of an object is NOT correct? (Symbols carry their usual meanings)
- A. s=ut+\frac{1}{2}at^{2}
- B. u=v-at
- C. u^{2}-v^{2}=2as ✓
- D. Distance travelled during n^{th}second=u+\frac{1}{2}a(2n-1)
Correct Answer: C. u^{2}-v^{2}=2as
Explanation
The correct third equation of motion is v^{2}-u^{2}=2as. Option C incorrectly states it as u^{2}-v^{2}=2as.
