This video tutorial explains motion graphs, focusing on distance-time graphs. It covers key terms like stationary, constant speed, acceleration, and deceleration. The video demonstrates how to interpret these graphs and calculate speed using distance over time. Examples, such as a Rhino's movement, illustrate these concepts. The tutorial also discusses how graph steepness indicates speed and how curved lines show acceleration or deceleration. Finally, it provides resources for further learning.

What does it mean if an object is stationary?

• It is accelerating.

• It is moving at a constant speed.

• It is not moving.

• It is decelerating.

What are the units for distance and time on a motion graph?

• Meters and minutes

• Kilometers and hours

• Meters and seconds

• Centimeters and seconds

What does a horizontal straight line on a motion graph indicate?

• The object is moving at a constant speed.

• The object is decelerating.

• The object is accelerating.

• The object is stationary.
