Question

Which of the following graphs has a slope that indicates an object whose velocity is zero

Answer 1

Answer:

The horizontal line.

Step-by-step explanation:

A horizontal line has a slope of 0. This would be expected on a graph where time is the x axis and distance is the y axis. Time would elapse but the distance would not change.

Answer 2

Answer:

The correct option is 1.

Step-by-step explanation:

We need to find a graph that indicates an object whose velocity is zero.

Velocity is the change in displacement with respect to time.

Let d represents displacement and t represent time.

$v=\frac{\text{Change in displacement}}{\text{change in time}}$

Velocity is 0.

$0=\frac{\text{Change in displacement}}{\text{change in time}}$

It means the slope of line must be 0.

A horizontal line has slope 0.

In option 1, the graph represents a line whose slope is 0. It means displacement is 0 for any interval of time. So, velocity is 0.

Therefore the correct option is 1.
