Speed-Time Graphs Flashcards

All 4 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 tell you?

The speed is constant (acceleration is zero).

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

False.
It means constant speed; the object is only stationary if that speed is 0.

On a speed-time graph with speed in m/s and time in seconds, what are the units of the gradient?

m/s$^2$ (metres per second per second).
