12/2 Speed and Graphs

Front

What is speed?

Back

The distance an object travels per unit of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

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

Front

If a biker travels 60 km in 2 hours, what is their speed?

Back

30 km/hr.

Front

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

Back

The object is at rest.

Front

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

Back

The object is moving quickly.

Front

What is average speed?

Back

Total distance traveled divided by total time taken.

Front

If an object travels 42 meters in 6 seconds, what is its average speed?

Back

7 m/s.

Front

What does it mean if an object has constant speed?

Back

The object covers equal distances in equal intervals of time.

Front

What is acceleration?

Back

The rate of change of velocity per unit of time.
