Chapter 16 S. 1&3

When is an object in motion? An object is in motion if it changes position relative to a reference point.
How do you know an object's speed and velocity? If you know the distance an object travels in a certain amount of time, you can calculate the speed of the object. When you know both the speed and direction of an objects motion, you know the velocity of the object.
How can you graph motion? You can show the motion of an object on a line graph in which you plot distance versus time.
What kind of motion does acceleration refer to? Increasing speed, Decreasing speed, Changing direction.
How is acceleration calculation? Acceleration = Fs-Is\T
What graphs can be used to analyze the motion of an accelerating object? You can use both a speed Vs. time graoh and a distance Vs. time graph to analyza the motion of an accelerating object.
