Physics facts

What does displacement indicate in kinematic definitions?

• The speed of an object at any given time

• The total time an object takes to stop

• How far an object ends up from its initial position

• The acceleration of an object over time

How is average velocity calculated?

• Displacement multiplied by time

• Displacement divided by the time interval over which that displacement occurred

• Speed divided by time

• Time divided by displacement

What does a position-time graph slope like a front slash (/) indicate?

• The object is stationary

• The object is moving toward the detector

• The object is moving away from the detector

• The object is moving in a circular path

What does a position-time graph slope like a back slash (\) indicate?

• The object is moving toward the detector

• The object is moving away from the detector

• The object is moving in a circular path

• The object is stationary

What aspect of a position-time graph indicates how fast an object is moving?

• The color of the graph

• The length of the graph

• The steepness of the slope

• The labels on the axes

How can you determine the speed of an object using a velocity-time graph?

• By measuring the area under the graph

• By looking at the vertical axis

• By observing the color of the graph

• By measuring the length of the graph

What does the position of the velocity-time graph above or below the horizontal axis indicate?

• The object's color

• The speed of the object

• The direction of the object's motion

• The weight of the object

How can you determine the distance an object has traveled from a velocity-time graph?

• By calculating the total time

• By finding the peak point

• By determining the area between the graph and the horizontal axis

• By counting the grid lines

According to the text, what is not possible to determine from a velocity-time graph?

• The speed of the object

• The distance traveled

• The direction of motion

• The exact location of the object

What does acceleration tell us about an object's motion?

• The potential energy

• The change in speed per second

• The color change during motion

• The total distance traveled
