The document discusses speed-time graphs and how they represent different types of motion: no movement, constant speed, constant speed at different rates, acceleration, and constant acceleration. It provides examples of how speed-time graphs would appear for an object falling with constant acceleration due to gravity and notes that the area under the graph represents the distance traveled.

Speed - time graphs speed time
No movement speed time
Constant speed speed time
Constant speed How would the graph speed look different for a faster constant speed? time
Constant speed speed fast time
Constant speed How would the graph speed look different for a slower constant speed? fast time
Constant speed speed fast slow time
Getting faster? (accelerating) speed time
Getting faster? (accelerating) speed Constant acceleration time
Getting faster? (accelerating) speed The area under the graph gives the distance travelled time
Example: speed time
A dog falling from a tall building (no air resistance) speed time
A dog falling from a tall building (no air resistance) speed time
A dog falling from a tall building (no air resistance) speed Area = height of building time
Be careful! speed distance time time
No movement speed distance time time
Constant speed speed distance time Area = distance travelled time
Constant acceleration speed distance time Area = distance travelled time
