Flashcard - Speed & Acceleration Graphs

Front

What does a constant speed graph look like?

Back

A straight horizontal line on a distance-time graph, indicating that distance increases steadily over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

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

Back

A steep slope indicates a high speed.

Front

What does a flat line on a speed-time graph represent?

Back

A flat line indicates constant speed; the object is moving at the same speed over time.

Front

What is the unit of speed?

Back

The standard unit of speed is meters per second (m/s).

Front

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

Back

A downward slope indicates that the object is decelerating (slowing down).

Front

If a car travels 100 meters in 5 seconds, what is its speed?

Back

Speed = 100 m / 5 s = 20 m/s.

Front

What does it mean if the speed-time graph is above the time axis?

Back

It means the object is moving forward; if it were below, it would indicate reverse motion.

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).
