MCQ
If a particle is moving along straight line with increasing speed, then
- AIts acceleration is negative
- ✓Its acceleration may be decreasing
- CIts acceleration is positive
- DBoth $(b)$ and $(c)$
✓
Answer
Correct option: B.
Its acceleration may be decreasing
b
(b)
(b)
If the speed of body is increasing then acceleration is in the direction of velocity.
It may be positive or negative.
If acceleration is in negative direction then acceleration is increasing but in negative side, so it will be called as decreasing.
