Distance vs Time

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically expressed in units like km/hr.

Front

What is the formula to calculate speed?

Back

Speed = Distance / Time

Front

What are the units of distance?

Back

Common units of distance include kilometers (km), meters (m), and miles.

Front

What are the units of time?

Back

Common units of time include seconds (s), minutes (min), and hours (hr).

Front

On a distance vs time graph, what does a horizontal line represent?

Back

A horizontal line indicates that the object is at rest (not moving).

Front

On a distance vs time graph, what does a straight diagonal line represent?

Back

A straight diagonal line indicates that the object is moving at a constant speed.

Front

What does the slope of a distance vs time graph represent?

Back

The slope represents the speed of the object; steeper slopes indicate higher speeds.

Front

If a car travels 100 km in 2 hours, what is its speed?

Back

Speed = 100 km / 2 hr = 50 km/hr.

Front

What is the independent variable in a distance vs time graph?

Back

The independent variable is time, which is plotted on the x-axis.

Front

What is the dependent variable in a distance vs time graph?

Back

The dependent variable is distance, which is plotted on the y-axis.
