Velocity of a freely falling stone
Velocity is a vector.
Describe the velocity of the stone as it falls through the air.
Assume there is no air resistance.
Write your answer first. You can study the marking guidance whenever you need it.
Study the marking See what earns credit and compare it with a full-mark answer.
Marking points
- 1 State that the magnitude, or speed, increases uniformly.
- 2 State that the direction remains constant as it falls.
Full-mark answer
As the stone falls with no air resistance, the magnitude of its velocity increases uniformly while its direction remains constant downward.
Why this answer loses marks
The velocity stays constant.
With no air resistance, the stone accelerates, so the magnitude of velocity increases.
