8.F.1 + 8.F.3 + 8.F.5 Flashcard

Front

What does it mean for an object to be moving at a constant speed?

Back

An object is moving at a constant speed when it covers equal distances in equal intervals of time, without speeding up or slowing down.

Front

How can you determine if a function is linear or nonlinear?

Back

A function is linear if it can be represented by a straight line on a graph, meaning it has a constant rate of change. If the graph is curved, it is nonlinear.

Front

What is the definition of speed in terms of distance and time?

Back

Speed is defined as the distance traveled divided by the time taken to travel that distance, usually expressed in units like miles per hour or meters per second.

Front

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

Back

A horizontal line indicates that the object is stationary, meaning it is not moving.

Front

What is the significance of the slope of a line on a graph?

Back

The slope of a line on a graph represents the rate of change; in a distance-time graph, it indicates speed.

Front

What does it mean if the speed of an object is increasing?

Back

If the speed of an object is increasing, it means the object is accelerating, covering more distance in the same amount of time.

Front

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

Back

A steep slope indicates a high speed, meaning the object is covering a large distance in a short amount of time.

Front

What is the formula for calculating the rate of change?

Back

The rate of change can be calculated using the formula: Rate of Change = (Change in Value) / (Change in Time).

Front

What does it mean for an object to be 'parked' on a graph?

Back

An object is 'parked' on a graph when it is not moving, represented by a horizontal line on a distance-time graph.

Front

How can you identify a section of a graph where an object is moving the slowest?

Back

You can identify the slowest section of a graph by looking for the section with the least steep slope.
