Distance vs. Time and Speed Vs. Time Graphs

Front

What is the equation to calculate speed?

Back

speed = distance/time

Front

What does a position vs. time graph show when the line is straight and sloping upwards?

Back

The object is moving at a constant speed away from the start.

Front

What does a position vs. time graph show when the line is horizontal?

Back

The object is at rest.

Front

What does a position vs. time graph show when the line is sloping downwards?

Back

The object is moving at a constant speed towards the start.

Front

What does a curve in a position vs. time graph indicate?

Back

The object is accelerating.

Front

What does negative acceleration mean?

Back

The object is slowing down.

Front

What is the unit of speed?

Back

meters per second (m/s) or kilometers per hour (km/h).

Front

If an object travels 100 meters in 5 seconds, what is its speed?

Back

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