Question
The motion of an aeroplane on the runway before take-off is ______.
Options
Linear
Non-linear
Circular
Uniform linear
Non-uniform linear
Uniform circular
Non-uniform circular
Random
Solution
The motion of an aeroplane on the runway before take-off is non-uniform linear.
Explanation:
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.
