In a lab, we measure how fast a ball travels down the hall. We measure the distance traveled, and the time elapsed. If we made a graph of the data, which of the following would go on the X-axis of the graph?
Distance
Time
speed
acceleration

A positive acceleration means that the object is:
speeding up
slowing down
going backwards
going in circles

A negative acceleration means that the object is:
speeding up
slowing down
going backwards
going in circles
