If velocity - time graph is parallel to time axis, the-

Concept:

• Velocity: The rate of change of position i.e. rate of displacement with time is called velocity.

Where s2 = displacement of the object at t2 and s1 = displacement of the object at t1

• It is a vector quantity having the symbol.

Explanation:

If the velocity-time graph is parallel to the time axis, then

In the above graph 

• The body is moving with a constant velocity.
• Due to moving with constant velocity, acceleration is zero.
• The net displacement can be found in the area under the curve.

So, all the given statements are correct.
