12/3 Speed and Graphs

Front

What is speed?

Back

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

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

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

Back

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

Front

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

Back

A steep slope indicates that the object is moving quickly; the steeper the slope, the faster the object is moving.

Front

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

Back

A downward slope indicates that the object is returning to the starting point.

Front

What is the unit of distance in the metric system?

Back

The unit of distance in the metric system is the meter (m).

Front

What is the significance of the y-axis on a distance-time graph?

Back

The y-axis represents the distance traveled by the object.

Front

What is the significance of the x-axis on a distance-time graph?

Back

The x-axis represents the time elapsed during the object's movement.

Front

If an object travels 100 meters in 4 seconds, what is its average speed?

Back

Average speed = 100 m / 4 s = 25 m/s.

Front

What does it mean if an object is moving at a constant speed?

Back

It means the object covers equal distances in equal intervals of time without speeding up or slowing down.
