A hummingbird averages a speed of about 45 km/hour (Cool facts: They visit up to 1000 flowers per day, and reach maximum speed, while diving, up to 160 km/hour!). Ruby-noted hummingbirds take a non-stop trip across Gulf of Mexico in which they fly for 18 hours straight! How far is the trip across the Gulf of Mexico at their average speed?

In the process of delivering mail, a postal worker walks 161 m, due east from his truck. He then turns around and walks 194 m, due west from his truck. What is the worker's displacement relative to his truck?
33 m, due west
33 m, due east

An alpaca is traveling at 10 m/s when it speeds up to 30 m/s in a span of 4 s. What distance does it travel?
160 m
120 m
80 m
40 m
What explains why objects resist changes in their state of motion?
gravity
inertia
force
friction
True or False: objects with greater mass require more force to accelerate when compared to objects with less mass.
True
False
Temperature, mass and energy are scalar quantities because:
they have both magnitude and direction
they have magnitude only without direction
they have direction only without magnitude
they are measured in the same units

gravity
normal
a push or pull
friction

A book is falling from a table
A book is being pulled across a table
