Understanding Motion and Graphs

What is a motion diagram and what does it represent?

• A motion diagram represents the position, direction, and speed of an object at different moments in time.

• A motion diagram illustrates the color and shape of an object over time.

• A motion diagram shows only the speed of an object at a single moment.

• A motion diagram represents the temperature changes of an object during motion.

How can you determine the direction of motion from a motion diagram?

• The direction of motion is indicated by the sequence of positions and the arrows in the motion diagram.

• The direction can be inferred from the speed of the object only.

• The motion diagram does not provide any information about direction.

• The direction of motion is determined by the color of the arrows.

In a position vs. time graph, what does a horizontal line indicate?

• The object is at rest.

• The object is accelerating.

• The object is changing direction.

• The object is moving at a constant speed.

What does the slope of a position vs. time graph represent?

• The slope indicates the acceleration of the object.

• The slope shows the distance traveled by the object.

• The slope represents the time taken by the object.

• The slope represents the velocity of the object.

How do you calculate average speed from a distance and time?

• Average Speed = Total Time / Total Distance

• Average Speed = Total Distance / Total Time

• Average Speed = Distance + Time

• Average Speed = Distance - Time

If a car travels 100 km in 2 hours, what is its average speed?

• 25 km/h

• 100 km/h

• 50 km/h

• 75 km/h

What is the difference between distance and displacement?

• Distance is always greater than displacement.

• Distance and displacement are the same concept.

• Displacement measures the total time taken to travel.

• Distance is the total path length traveled; displacement is the shortest straight-line distance with direction.

If a person walks 3 km east and then 4 km west, what is their displacement?

• 3 km west

• 1 km east

• 4 km east

• 1 km west

How can you identify acceleration in a position vs. time graph?

• Acceleration is indicated by the curvature of the position vs. time graph.

• Acceleration can be identified by the slope of the graph only.

• Acceleration is represented by the area under the curve.

• Acceleration is shown by a straight line on the graph.

What does a negative slope in a position vs. time graph indicate?

• The object is accelerating forward.

• The object is at rest.

• The object is moving in a circular path.

• The object is moving backwards.
