Answer:
1. Motion - is the action or process of moving or of changing place or position; movement.
2. A reference point is a place or object used for comparison to determine if something is in motion.
An example of a reference point that is moving is when you look out the window of a car and notice that you are moving faster than the car next to you.
3. DISTANCE is a scalar quantity that refers to "how much ground an object has covered" during its motion. DISPLACEMENT is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
4. The official displacement formula is as follows:
s = sf – si
s = displacement
si = initial position
sf = final position
Distance = speed x time
5. -the rate of change of its position is called its SPEED.
-The information regarding the object's direction of motion is included in its velocity. The velocity of the object defines the speed as well as the direction of motion of the object.
-The acceleration of an object is defined as the rate of change of its velocity, or the change of its velocity per unit time.
