Question
A body is positively accelerating. Its ____
- Velocity decreases uniformly
- Velocity increases uniformly
- Acceleration increases uniformly
- Acceleration decreases uniformly
Hint:
Velocity increases uniformly
The correct answer is: Velocity increases uniformly
When a body is positively accelerating, its velocity increases uniformly.
If an object travels in a straight line and it's velocity increases or decreases by equal amounts in equal intervals of time, then the acceleration of the object is said to be uniform.

Mira plotted a s-t graph of her car journey by collecting data during a drive. She started from rest and slowly increased her velocity until it reached a particular value. Then she maintained a uniform motion. Lastly, she slowed down gradually to bring the car to a stop. Which of the following graphs would resemble the graph plotted by Mira?
