The position of a particle moving along the x -axis at certain times is given below :

t (s)	0	1	2	3
x (m)	–2	0	6	16

Which of the following describes the motion correctly

Uniform, accelerated

Uniform, decelerated

Non-uniform, accelerated

There is not enough data for generalization

Verified by Experts

The correct answer is:

Instantaneous velocity \(\mathbf{v} = \frac{\Delta x}{\Delta t}\)

By using the data from the table

\(v_1 = \frac{0 - (-2)}{1} = 2\,m/s, \quad v_2 = \frac{6 - 0}{1} = 6\,m/s\)

\(v_3 = \frac{16 - 6}{1} = 10 \, m/s\)

So, motion is non-uniform but accelerated.
