Question

1. on a velocity vs. time graph, what does a flat line indicate?

• a) the object is speeding up
• b) the object is slowing down
• c) the object is moving at a constant speed
• d) the object is stationary

1. what does an acceleration vs. time graph represent?

• a) how far an object has traveled
• b) the speed of an object
• c) how quickly the velocity is changing
• d) the direction of motion

1. which axis typically represents the independent variable in a graph?

• a) vertical axis (y - axis)
• b) horizontal axis (x - axis)
• c) both axes
• d) neither axis

Explanation:

1. Position vs. Time graph shows an object's position over time.
2. A straight - line on a Position vs. Time graph means constant speed as slope represents speed.
3. On a Velocity vs. Time graph, flat line means no change in velocity, so constant speed.
4. Acceleration is the rate of change of velocity, so an Acceleration vs. Time graph shows how quickly velocity is changing.
5. In a graph, the independent variable is typically plotted on the horizontal (x -) axis.

Answer:

1. C) Position vs. Time
2. A) The object is moving at a constant speed
3. C) The object is moving at a constant speed
4. C) How quickly the velocity is changing
5. B) Horizontal Axis (x - axis)
