Final answer:
The statement about the position vs time graph being a straight line for an object speeding up is False; it should show a curve. The claim regarding kinetic and potential energy when throwing a rock is False; energy conversion is the reverse of what the question suggests. The effect of the market revolution on the U.S. being significant is True.
Step-by-step explanation:
Answer to True/False Questions
Physics often deals with the behavior of objects and the forces acting on them. Let's address the questions in sequence:
Position vs Time Graph: The statement that the position vs time graph of an object that is speeding up is a straight line is False. When an object is speeding up, its velocity is changing, which means the slope of the line on a position vs time graph is changing. The graph would typically show a curve, indicating acceleration.
Kinetic and Potential Energy: The statement that throwing a rock into the air increases its kinetic energy and that the increase in velocity as it falls increases its potential energy is False. In fact, it is the opposite. As the rock is thrown up, its kinetic energy converts to potential energy, and as it falls, the potential energy converts back to kinetic energy.
Market Revolution Impacts: It is True that the market revolution brought many social and economic changes to the United States. This period was characterized by rapid expansion in industrialization, transportation, and communication, which had wide-ranging effects on the American economy and society.
