Velocity-Time Graphs

Front

What is a velocity-time graph?

Back

A graph that shows the relationship between the velocity of an object and time, illustrating how the object's speed changes over a period.

Front

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

Back

The object is accelerating in the positive direction.

Front

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

Back

The object is accelerating in the negative direction.

Front

What does a horizontal line on a velocity-time graph represent?

Back

The object is moving at a constant velocity.

Front

What does a slope of zero on a velocity-time graph indicate?

Back

The object is at rest.

Front

How do you calculate acceleration from a velocity-time graph?

Back

Acceleration is calculated as the change in velocity divided by the time taken for that change (slope of the graph).

Front

What does the area under the velocity-time graph represent?

Back

The displacement of the object over the time interval.

Front

What does it mean if the velocity is negative on a velocity-time graph?

Back

The object is moving in the opposite direction.

Front

How can you tell if an object is slowing down on a velocity-time graph?

Back

If the velocity is decreasing over time, indicated by a negative slope.

Front

What is the significance of the point where the graph crosses the time axis?

Back

It indicates the moment the object changes direction.
