Answer 1

The motion of an aeroplane on the runway before take-off is non-uniform linear.

An airplane's motion on the runway prior to takeoff is non-uniform linear motion because it moves in a straight line (linear motion) yet its speed does not remain constant (non-uniform) as it accelerates to prepare for takeoff.
