Question

Which of the following position-time graphs represents a constant velocity motion?

The position is represented by 'x' and time is represented by 't'.

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

The position-velocity graph is a graph plotting the change in position of an object with respect to time. When the plot is a straight inclined line as in this option, it means that there is an equal change in position for equal intervals of time. Hence, this represents constant velocity.

When the plot is a straight line parallel to the x-axis, it means that the position of the object is not changing with respect to time. i.e., the object is at rest.
