Position-Time Graphs

Front

What is a Position-Time Graph?

Back

A Position-Time Graph is a graphical representation that shows the position of an object at different times. The x-axis represents time, while the y-axis represents position.

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 positive slope on a Position-Time Graph represent?

Back

A positive slope indicates that the object is moving away from the starting point, meaning its position is increasing over time.

Front

What does a negative slope on a Position-Time Graph represent?

Back

A negative slope indicates that the object is moving towards the starting point, meaning its position is decreasing over time.

Front

How do you calculate the slope of a Position-Time Graph?

Back

The slope is calculated by dividing the change in position (rise) by the change in time (run). Slope = (Change in Position) / (Change in Time).

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 specific physical meaning; it is primarily used in Velocity-Time Graphs to represent distance.

Front

What is the significance of the y-intercept in a Position-Time Graph?

Back

The y-intercept represents the initial position of the object at time zero.

Front

If an object moves with constant speed, how does its Position-Time Graph look?

Back

The graph will be a straight line with a constant slope, indicating uniform motion.

Front

What does a steep slope on a Position-Time Graph indicate?

Back

A steep slope indicates a high speed, meaning the object is changing its position rapidly over time.

Front

What does a curve on a Position-Time Graph indicate?

Back

A curve indicates that the object's speed is changing; it could be accelerating or decelerating.
