Velocity-Time Graphs Flashcards

All 4 cards in this deck

What does the gradient of a velocity–time graph represent?

The acceleration of the object.

True or false? A horizontal line on a velocity–time graph shows that the object is stationary.

False. It shows constant velocity (zero acceleration); the object may still be moving.

On a velocity–time graph, how is an object whose acceleration is decreasing shown?

As a curve of decreasing gradient (still rising, but less steeply).

True or false? On a velocity–time graph, a steeper line means the object is moving faster.

False. A steeper line means a greater acceleration; the speed is read from the height of the line.
