Speed-Time Graphs Flashcards

All 6 cards in this deck

What does the gradient of a speed-time graph represent?

The acceleration.

What does a horizontal line on a speed-time graph show?

Constant (steady) speed — no acceleration.

What does a line sloping downwards on a speed-time graph show?

The object is slowing down (decelerating).

True or false? A horizontal line on a speed-time graph means the object has stopped.

False.
It means constant speed; the object is only stopped where the line is on the time axis (speed $= 0$).

On a speed-time graph, how can you tell which of two sections has the greater acceleration?

The steeper section has the greater acceleration.

How do you find the speed at a given time from a speed-time graph?
e.g. the speed at 10 seconds

Read up from $10$ on the time axis to the line, then straight across to the speed axis.
