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? If you know the distance an object travels in a certain amount of time, you can calculate the speed 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? Acceleration refers to increasing speed, decreasing speed, or changing direction.
How is acceleration calculated? To determine the acceleration of an object moving in a straight line, you must calculate the change in speed per unit of time.
What graphs can be used to analyze the motion of an accelerating object? You can use both a speed-versus-time graph and a distance-versus-time graph to analyze the motion of an accelerating object.
How do you know an object’s velocity? When you know both the speed and direction of an object’s motion, you know the velocity of the object.
