Speed-Time Graphs

Front

What is a Speed-Time Graph?

Back

A Speed-Time Graph is a visual representation that shows how the speed of an object changes over time.

Front

What does a flat line on a Speed-Time Graph indicate?

Back

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

Front

What does an upward slope on a Speed-Time Graph represent?

Back

An upward slope represents acceleration, meaning the object is speeding up.

Front

What does a downward slope on a Speed-Time Graph indicate?

Back

A downward slope indicates deceleration, meaning the object is slowing down.

Front

What does a horizontal line at zero speed mean?

Back

It means the object is stationary and not moving.

Front

How can you determine the speed of an object from a Speed-Time Graph?

Back

The speed can be determined by looking at the value on the vertical axis at a specific time.

Front

What does the area under the Speed-Time Graph represent?

Back

The area under the graph represents the distance traveled by the object.

Front

What does it mean if the Speed-Time Graph has a steep slope?

Back

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

Front

What is the significance of point C in a Speed-Time Graph?

Back

Point C often indicates a change in the motion of the object, such as acceleration.

Front

How can you tell if an object is returning to the starting point on a Speed-Time Graph?

Back

If the graph shows a downward slope after reaching a peak speed, the object is returning to the starting point.
