Physics · MOTION IN A STRAIGHT LINE

The velocity of an object is given by \( v = \frac{dx}{dt} \). When the position-time graph is a straight line inclined to the time axis, the instantaneous velocity is:

1. Zero / शून्य
2. Increasing with time / समय के साथ बढ़ता है
3. Constant and non-zero / नियत और शून्येतर
4. Decreasing with time / समय के साथ घटता है
