Acceleration Graphs II

Front

What does a graph showing negative velocity that is getting faster indicate?

Back

The object is moving in the negative direction and its speed is increasing.

Front

What does a graph showing positive velocity that is getting slower indicate?

Back

The object is moving in the positive direction but its speed is decreasing.

Front

Which motion diagram represents an object slowing down in the positive direction?

Back

Diagram C.

Front

How do you determine instantaneous velocity from a graph?

Back

Instantaneous velocity is the slope of the tangent line to the curve at a specific point on the graph.

Front

What does a graph showing negative velocity that is getting slower indicate?

Back

The object is moving in the negative direction and its speed is decreasing.

Front

Define acceleration in the context of motion graphs.

Back

Acceleration is the rate of change of velocity over time, represented by the slope of the velocity-time graph.

Front

What is the significance of a horizontal line on a velocity-time graph?

Back

A horizontal line indicates constant velocity; the object is not accelerating.

Front

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

Back

A positive slope indicates that the object is accelerating in the positive direction.

Front

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

Back

A negative slope indicates that the object is accelerating in the negative direction.

Front

How can you tell if an object is at rest from a velocity-time graph?

Back

If the graph is at the zero line (x-axis), the object is at rest.
