Question
In which of the following cases a body is said to be accelerating ?
- Speeding up
- Slowing down
- Not moving at all
- Moving at a uniform speed
Hint:
Speeding up
The correct answer is: Speeding up
In the case of speeding up the body is said to be accelerating. Acceleration will be positive.
Negative acceleration is known as deceleration.
