Distance-Time Graph Analysis

The video tutorial explains how to interpret distance-time graphs to understand motion. It covers the basics of graph plotting, differentiates between uniform and non-uniform motion, and demonstrates how to calculate speed using graphs. The tutorial also analyzes various graph types to explain motion changes, compares the motion of two objects, and interprets graphs showing return motion to the starting point.

What does a straight line on a distance-time graph indicate about the motion of an object?

• The object is moving with uniform speed.

• The object is accelerating.

• The object is at rest.

• The object is moving with decreasing speed.

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

• By measuring the distance between two points on the y-axis.

• By calculating the slope of the line on the graph.

• By finding the area under the graph.

• By counting the number of points on the graph.

What does a curved line on a distance-time graph suggest about the object's motion?

• The object is moving with uniform speed.

• The object is at rest.

• The object is accelerating or decelerating.

• The object is moving backward.

If a distance-time graph shows a horizontal line, what does it indicate about the object?

• The object is at rest.

• The object is moving backward.

• The object is accelerating.

• The object is moving with constant speed.

What does it mean if the distance-time graph of an object is a straight line parallel to the x-axis?

• The object is moving backward.

• The object is at rest.

• The object is accelerating.

• The object is moving with constant speed.

How can you tell which object is moving faster when comparing two distance-time graphs?

• The object with the more curved line is moving faster.

• The object with the higher y-intercept is moving faster.

• The object with the longer line is moving faster.

• The object with the steeper line is moving faster.

In a distance-time graph, what does a steeper slope indicate?

• The object is at rest

• Faster speed

• Constant speed

• Slower speed

What does a decreasing distance on a distance-time graph indicate?

• The object is accelerating.

• The object is moving towards the starting point.

• The object is moving away from the starting point.

• The object is at rest.

How is average speed calculated from a distance-time graph?

• By counting the number of points on the graph.

• By measuring the area under the graph.

• By finding the slope of the graph.

• By dividing the total distance by the total time.

What can be inferred if a distance-time graph shows a line returning to the origin?

• The object is accelerating.

• The object is moving away from the starting point.

• The object is at rest.

• The object is returning to the starting point.
