Position-Time Graph Analysis

The video tutorial explains how to interpret position-time graphs to understand an object's motion. It covers analyzing graphs for stationary objects, forward and backward motion, and uniform motion. The tutorial emphasizes the importance of slope in determining velocity and direction, using examples to illustrate concepts like positive and negative slopes, and how they relate to motion direction.

What does a position-time graph primarily show?

• The speed of an object

• The position of an object over time

• The acceleration of an object

• The direction of an object

If the slope of a position-time graph is zero, what does it indicate about the object's motion?

• The object is at rest

• The object is moving backward

• The object is moving forward

• The object is accelerating

What does a negative slope on a position-time graph indicate?

• The object is moving backward

• The object is at rest

• The object is moving forward

• The object is accelerating

How do you calculate the slope of a position-time graph?

• Distance divided by time

• Run divided by rise

• Rise divided by run

• Time divided by distance

What does a constant positive slope on a position-time graph indicate?

• The object is moving backward

• The object is at rest

• The object is accelerating

• The object is moving forward with uniform motion

In a position-time graph, what does a horizontal line segment represent?

• The object is at rest

• The object is moving backward

• The object is moving forward

• The object is accelerating

What does a negative velocity indicate in the context of a position-time graph?

• The object is at rest

• The object is accelerating

• The object is moving backward

• The object is moving forward

How can you determine the direction of motion from a position-time graph?

• By checking the graph's title

• By looking at the graph's color

• By analyzing the slope's sign

• By measuring the graph's width

What does a slope of -1 m/s on a position-time graph indicate?

• The object is moving forward at 1 m/s

• The object is moving backward at 1 m/s

• The object is accelerating at 1 m/s²

• The object is at rest

What is the significance of a uniform motion in a position-time graph?

• The object is at rest

• The object is changing direction

• The object is moving at a constant speed

• The object is accelerating
