A stone is projected from the top of a cliff and moves freely under gravity. The stone is modelled as a particle and air resistance is modelled as negligible.
Identify the quantity that remains constant throughout the flight.
Circle your answer.
the speed of the stone
the vertical component of the velocity
the horizontal component of the velocity
the vertical displacement of the stone
