Question

A velocity–time graph is a straight line with zero slope. What does this indicate about the motion?

Options

• Uniform acceleration

• Zero velocity

• Constant velocity, zero acceleration

• Constant displacement

Answer 1

Constant velocity, zero acceleration

Explanation:

Zero slope in a vv–tt graph means velocity is constant and does not change with time, so acceleration (slope) is zero. Thus, the object moves with constant velocity and zero acceleration.
