(99 Points) In the Position versus Time Graph of an object moving in a straight line, does the graph show acceleration during the interval from time equals two hours to time equals three hours?

No, the object is not accelerating because acceleration occurs if the object has a change in speed or direction.

In position time graphs, otherwise known as distance time graphs, acceleration/decceleration occurs when the line curves, which looks like the picture I've included.

In hours 2 to 3, the object does not accelerate, but instead stays at a constant speed of 20m per hour.
