To fully describe the motion of an object you must fully describe its what?

well the main part to this is time. you have to explain the object's acceleration and velocity with reference to time. I'll give you some examples of phrases to use :
from t=0 to t=10 the object started from rest and was moving with constant acceleration of 5m/s^2
from t=10 to t=15 the object is moving with constant velocity of 50m/s
from t=15 to t=40 the object's velocity decreased with constant retardation (deceleration) of 2m/s^2 until it came to rest again
im not sure if all the numbers will add up on that one, juz kinda wrote the figures as i thought of the phrase

Why do you need to include a reference point when you describe the motion of an object?
Motion is relative. There must be something to compare it to.
What point must be chosen to determine the motion of an object?
A reference point must be chosen to determine the motion of an object.
Must an object always have the same motion?
No, of course not! We ourselves we change our motion!
What conditions must exist for an object to be in uniform motion?
In order for an object to be in constant uniform motion ... that is, un-accelerated, with constant speed and direction of motion ... the vector sum of all forces acting on it must be zero.
What must be true about an object that serves as a reference point?
motion

Motion is relative. There must be something to compare it to.

A reference point must be chosen to determine the motion of an object.
When you describe motion you must have what?

An object that has kinetic energy must be what?
In motion
Must an object always have the same motion?
No, of course not! We ourselves we change our motion!
What forces must be changed the motion of an object?
Forces must be greater than zero and impact the object.
What must happen for an object to be in motion?
Gravity I guess :-)
What conditions must exist for an object to be in uniform motion?
In order for an object to be in constant uniform motion ... that is, un-accelerated, with constant speed and direction of motion ... the vector sum of all forces acting on it must be zero.
What must be true about an object that serves as a reference point?
motion
How do you tell when an object is in motion?
The fact is that it always is ... in relation to something. For an object to be at "rest" there must be a second object to compare it with.
What is required for a force to do work on an object?
in the same direction as the object's motion.
What is the only requirement for an object to be in projectile motion?
Gravity must be the only force acting on the object.
