How can you tell from a speed vs. time graph if an object is accelerating?

The slope of the line is positive

What does a negative acceleration represent on a speed vs. time graph?

Slowing down

If Clara's speed vs. time graph is a straight, horizontal line, what can be said about her motion?

She is moving at a constant speed

What does a positive slope on a speed vs. time graph indicate?

The object is accelerating.

How is acceleration represented on a speed vs. time graph?

Positive slope

If a line on a speed vs. time graph is steep, what does it indicate?

Larger acceleration

What does a negative slope on a speed vs. time graph signify?

Deceleration
