Speed vs Time Graphs

Front

What does a speed vs time graph represent?

Back

A speed vs time graph shows how the speed of an object changes over time.

Front

What does a horizontal line on a speed vs time graph indicate?

Back

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

Front

What does a line sloping upwards on a speed vs time graph represent?

Back

A line sloping upwards indicates that the object is gradually speeding up.

Front

What does a line sloping downwards on a speed vs time graph represent?

Back

A line sloping downwards indicates that the object is gradually slowing down.

Front

What does a flat line at the bottom of the graph indicate?

Back

A flat line at the bottom indicates that the object is at rest (not moving).

Front

What is acceleration?

Back

Acceleration is the rate of change of speed over time.

Front

What is deceleration?

Back

Deceleration is a decrease in speed, or negative acceleration.

Front

How can you determine if an object is accelerating from a speed vs time graph?

Back

If the line on the graph is sloping upwards, the object is accelerating.

Front

How can you determine if an object is decelerating from a speed vs time graph?

Back

If the line on the graph is sloping downwards, the object is decelerating.

Front

What does a steep slope on a speed vs time graph indicate?

Back

A steep slope indicates a high rate of acceleration or deceleration.
