Distance Time Graphs and SPEED

Front

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

Back

A straight line indicates that an object’s speed is constant.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

If a person jogs for 2 hours at a speed of 12 km/hr, how far do they go?

Back

24 km

Front

What does acceleration mean in the context of a distance-time graph?

Back

Acceleration refers to an increase in speed over time.

Front

What does deceleration mean in the context of a distance-time graph?

Back

Deceleration refers to a decrease in speed over time.

Front

What is the speed of an object that travels 50 feet in 5 seconds?

Back

10 ft/s

Front

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

Back

A horizontal line represents no motion.

Front

What is the unit of speed in the metric system?

Back

Kilometers per hour (km/hr) or meters per second (m/s).

Front

How can you determine if an object is speeding up on a distance-time graph?

Back

If the slope of the line is increasing, the object is speeding up.

Front

How can you determine if an object is slowing down on a distance-time graph?

Back

If the slope of the line is decreasing, the object is slowing down.
