Speed, Velocity Acceleration, Graphs

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is the unit of acceleration?

Back

The unit we use to measure acceleration is meters/second/second.

Front

What does a negative acceleration indicate?

Back

A negative acceleration means that the object is slowing down.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is velocity?

Back

Velocity is speed in a given direction.

Front

What is the unit of speed?

Back

The unit of speed is meters/second.

Front

What does a speed-time graph represent?

Back

A speed-time graph shows how speed changes over time.

Front

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

Back

A flat line indicates that the object is moving at a constant speed.

Front

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

Back

An upward slope indicates that the object is accelerating.

Front

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

Back

A downward slope indicates that the object is decelerating.
