ICP: Speed/Time Graphs

Front

What does a speed/time graph represent?

Back

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

Front

What does a horizontal line on a speed/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/time graph represent?

Back

A line sloping upwards indicates that the object is accelerating (speeding up).

Front

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

Back

A line sloping downwards indicates that the object is decelerating (slowing down).

Front

What does a flat line at zero speed indicate on a speed/time graph?

Back

A flat line at zero speed indicates that the object is at rest.

Front

What is negative acceleration?

Back

Negative acceleration, or deceleration, occurs when an object is slowing down.

Front

What is positive acceleration?

Back

Positive acceleration occurs when an object is speeding up.

Front

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

Back

The speed of an object can be determined by looking at the value on the vertical axis at any given time.

Front

What does the area under the speed/time graph represent?

Back

The area under the speed/time graph represents the distance traveled by the object.

Front

What is the significance of the slope of a speed/time graph?

Back

The slope of a speed/time graph represents the acceleration of the object.
