Final answer:
Contemporary films are shot and projected at 24 frames per second to prevent flicker, not 16 frames as stated. Additionally, a position vs time graph for an object speeding up is a curve, not a straight line.
Step-by-step explanation:
The statement about contemporary films being shot and projected at 16 frames per second is false. Modern movies are typically projected at 24 frames per second, which is sufficient to create the illusion of continuous motion and prevent flicker to the human eye. The 'flicker fusion threshold' is the frequency at which an intermittent light stimulus is perceived to be completely steady by the human eye. This threshold is generally above 16 frames per second, making 24 frames the industry standard for smooth motion without flicker.
In regards to the given reference statement, "True or False: The position vs time graph of an object that is speeding up is a straight line," the answer is false. A position vs time graph for an object that is speeding up will be represented by a curve that gets steeper as time moves forward.
This is because the slope of the graph (which represents velocity) is constantly increasing as the object speeds up, resulting in a non-linear graph.
