A race car is travelling 300 miles in 2 hours. Is this enough information to tell the car's velocity? Why or why not?
no, the car's direction of motion is not given

is the Earth experiencing acceleration?
Yes, it is constantly turning on its axis (rotation) and moving around the sun (revolution)

on a graph showing speed, a horizontal line represents

Why could it be important to use velocity instead of speed when you describe how a storm is moving?
In order to keep everyone safe, we need to know how fast the storm is moving (speed) as well as what direction it is moving in (velocity). That way people in the path of the storm can make necessary preparations.

on a graph showing an object's speed, what variable goes on the x-axis, and what variable goes on the y-axis?
