Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like km/min or m/s.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What does a line moving away from the x-axis on a graph indicate?

Back

It indicates that the object is moving away from a reference point.

Front

If an object travels 60 miles in 1 hour, what is its speed?

Back

60 miles per hour.

Front

What is the speed of an object that travels 12 meters in 2 seconds?

Back

6 m/s.

Front

What does it mean if the speed is constant?

Back

It means the object is traveling the same distance in equal intervals of time.

Front

What is the significance of the slope of a line on a speed-time graph?

Back

The slope represents the speed of the object; a steeper slope indicates a higher speed.

Front

If you have 150 miles of gas and need to travel 180 miles, do you need to stop for gas?

Back

Yes, you will run out of gas before reaching your destination.

Front

What is the unit of speed in the metric system?

Back
