12/2 Speed and Graphs

Front

What is speed?

Back

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

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 speed graph represent?

Back

A flat line on a speed graph represents that the object is stationary or at rest.

Front

What does an upward sloping line on a speed graph indicate?

Back

An upward sloping line indicates that the object is increasing in speed, or accelerating.

Front

What does a downward sloping line on a speed graph represent?

Back

A downward sloping line indicates that the object is decreasing in speed, or slowing down.

Front

What is constant speed?

Back

Constant speed means that an object is traveling at the same speed over a period of time, represented by a straight line on a speed graph.

Front

If a car travels 160 kilometers in 5 hours, what is its average speed?

Back

32 km/hr.

Front

What does the term 'acceleration' mean?

Back

Acceleration refers to the rate of change of velocity of an object, indicating how quickly it is speeding up.

Front

What is the speed of an object at a specific point in time?

Back

The speed of an object at a specific point in time can be found by calculating the distance traveled at that moment divided by the time taken.

Front

What does it mean if a graph shows a steep slope?

Back

A steep slope on a speed graph indicates a high speed or rapid acceleration.
