Review: Position-Time Graphs

Front

What does a position-time graph represent?

Back

A position-time graph represents the position of an object over time, showing how far it has moved from a reference point.

Front

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

Back

A horizontal line indicates that the object is at rest, meaning its position does not change over time.

Front

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

Back

A straight diagonal line indicates that the object is moving at a constant speed.

Front

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

Back

A curved line indicates that the object is accelerating, meaning its speed is changing over time.

Front

What is the unit for position in a position-time graph?

Back

The unit for position is typically meters (m).

Front

What is the unit for time in a position-time graph?

Back

The unit for time is typically seconds (s).

Front

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

Back

A negative slope indicates that the object is moving in the negative direction (backward).

Front

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

Back

A positive slope indicates that the object is moving in the positive direction (forward).

Front

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

Back

The speed can be determined by calculating the slope of the line on the graph; steeper slopes indicate higher speeds.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
