Position-Time Graphs

Front

What does a position-time graph represent?

Back

A position-time graph represents the position of an object as a function of time, showing how far the object is from a reference point at different times.

Front

What does a straight line on a position-time graph indicate?

Back

A straight line on a position-time graph indicates that the object is moving at a constant speed.

Front

What does a slope of zero on a position-time graph indicate?

Back

A slope of zero indicates that the object is at rest and not changing its position over time.

Front

How can you determine the speed of an object from a position-time graph?

Back

The speed of an object can be determined by calculating the slope of the line on the position-time graph; a steeper slope indicates a higher speed.

Front

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

Back

A negative slope indicates that the object is moving in the opposite direction (back towards the starting point).

Front

What does the area under the curve represent in a position-time graph?

Back

In a position-time graph, the area under the curve does not have a physical meaning; it is primarily used in velocity-time graphs to represent distance.

Front

What does it mean if the position-time graph is curved?

Back

A curved position-time graph indicates that the object's speed is changing; it could be accelerating or decelerating.

Front

How can you identify an object moving away from the starting point on a position-time graph?

Back

An object is moving away from the starting point if the position values are increasing over time.

Front

What is the significance of the initial position on a position-time graph?

Back

The initial position is the value of the position at time zero, indicating where the object started its motion.

Front

How do you interpret a horizontal line on a position-time graph?

Back

A horizontal line indicates that the object is stationary; its position does not change over time.
