P.5A - Understanding Motion Through Graphs Review

Front

What does a horizontal line on a position vs. time graph indicate?

Back

The object is stationary.

Front

What does a steep slope on a position vs. time graph represent?

Back

The object is moving quickly.

Front

What does a negative slope on a position vs. time graph indicate?

Back

The object is moving back towards the starting position.

Front

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

Back

The object is accelerating.

Front

What does a flat line on a velocity vs. time graph represent?

Back

The object is moving at a constant velocity.

Front

What does a downward slope on a velocity vs. time graph indicate?

Back

The object is decelerating.

Front

How can you determine the speed of an object from a position vs. time graph?

Back

By calculating the slope of the line.

Front

What does the area under a velocity vs. time graph represent?

Back

The displacement of the object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a velocity vs. time graph with a line that slopes downward indicate?

Back

The object is slowing down.
