b. Emiliee's graph was a velocity-time graph, and Fred's graph was a distance-time graph.

a. Emiliee's graph was a distance-time graph, and Fred's graph was a velocity-time graph.

c. They were both drawing velocity-time graphs.

d. They were both drawing distance-time graphs.

Which of the following best describes an object's velocity?

c. The airplane travels southeast at 283 mph.

b. A boy runs near the school on a curvy path through the woods at a rate of 5 mph.

d. The horse gets loose and runs generally northwest at a quick pace.

The velocity of a school bus over the course of a trip is shown below. Which of the following is true about sections 1 and 3?

The acceleration during sections 1 and 3 are the same.

The positive acceleration during section 1 is slower than the negative acceleration during section 3.

There is no way to know which section is showing a slower acceleration.

What is happening from 0 to 5 seconds?

c. The object is moving away from start at a constant speed

What is happening from 0 to 5 seconds?

B. the car is traveling at a constant speed

Which interpretation describes the following graph?

Tom left his home for a run, but he was unfit and gradually came to a stop!

Tom ran from his home to the bus stop and waited. He realized that he had missed the bus so he walked home.

Tom skateboarded from his house, gradually building up speed. He slowed down to avoid some rough ground, but then speeded up again.

After the party, Tom walked slowly all the way home.

Which is NOT an example of acceleration?

a car going 55 mph on a straight road

The moon accelerates because it is

continuously changing direction.

constantly increasing its speed to stay in orbit.
