Per4 Review Flashcard #1 - Distance vs. Time & Speed vs. Time Graphs

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line indicates that the object is not moving; it is at rest.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a high speed; the steeper the slope, the faster the object is moving.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a downward slope on a speed-time graph represent?

Back

A downward slope indicates negative acceleration, meaning the object is slowing down.

Front

What is constant velocity?

Back

Constant velocity means an object is moving at a steady speed in a straight line without changing direction.

Front

What does an upward slope on a speed-time graph indicate?

Back

An upward slope indicates positive acceleration, meaning the object is speeding up.

Front

How can you identify constant speed on a distance-time graph?

Back

Constant speed is represented by a straight line with a constant slope on a distance-time graph.

Front

What does the area under a speed-time graph represent?

Back

The area under a speed-time graph represents the total distance traveled by 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).
