position and motion
directions: complete these paragraphs by writing the correct terms on the lines. some terms might be used more than once.

to describe an object’s (1.) position , you must first choose a(n) (2.) reference point as a starting place. from there, you must specify the (3.) direction to the object and the (4.) distance in which it lies from the starting place. if you are giving directions to two objects located in different directions from the same (5.) reference point , it can sometimes be helpful to describe one object as being in the (6.) positive direction from that place and the other in the (7.) negative direction.

an object is in (8.) motion any time its (9.) position is changing. in most cases, such a change involves changes in (10.) direction and (11.) distance from the starting point. however, if an object returns to its starting point, its (12.) __________ is zero, even though it might have traveled a considerable (13.) displacement .

Explanation:

To solve this fill - in - the - blank problem about position and motion, we use the basic concepts of kinematics:

Step 1: Analyze the first paragraph about position

• For (1), the main topic is about describing an object's location, so the term is "position".
• For (2), to describe position, we need a starting place which is a "reference point".
• For (3), when describing position relative to the reference point, we need to specify the "direction" to the object.
• For (4), along with direction, we need to specify the "distance" from the reference point.
• For (5), when dealing with two objects, they can be in different directions from the same "reference point".
• For (6) and (7), to differentiate directions, we can use "positive" and "negative" directions.

Step 2: Analyze the second paragraph about motion

• For (8), an object is in "motion" when its state of being at a place is changing.
• For (9), the thing that changes when an object is in motion is its "position".
• For (10) and (11), a change in position usually involves changes in "direction" and "distance" from the starting point.
• For (12), if an object returns to its starting point, its "displacement" (which is the change in position) is zero.
• For (13), even if displacement is zero, the object might have traveled a considerable "distance".
