Mathematics · Motion in a Straight Line
The following options present relations about displacement, velocity, and acceleration for the motion of a particle in general. Choose the incorrect relation (where vav is average velocity and aav is average acceleration):
- 1None of the above relations are incorrect
- 2aav = v(t2) - v(t1)t2 - t1
- 3vav = r(t2) - r(t1)t2 - t1
- 4vav = 12 [v(t1) + v(t2)]✓
Correct answer
vav = 12 [v(t1) + v(t2)]
