Question

How does the graph of velocity vs. time look for something with a constant positive acceleration?

a.a horizontal line.
b. an upward sloping straight line.
c.a downward sloping straight line.
d.a curving line with upward slope.

Answer 1

The correct answer is option b.

Step-by-step explanation:

In velocity vs time graph, vertical axis represent velocity vector and horizontal axis represents time. The slope of the line obtained in this graph is equal to the acceleration.

`Slope= (Velocity)/(Time)=Acceleration`

• If the line is straight makes an acute angle with horizontal axis then it is considered as positive acceleration.
• If the line is straight makes an obtuse angle with horizontal axis then it is considered as negative acceleration or deceleration.
