Is force necessary to change the speed or direction of a body?
Yes, force is necessary to change any motion of an object. The force can, for example be gravity or friction. Without these two factors, an object would continue moving in its original velocity (speed and direction) in eternity.
When do you say that an object is in circular motion?
Seems to me that either of the following could settle that issue: Necessary and sufficient: -- The object is in motion AND there exists a point from which the distance to the object is constant. Sufficient but not necessary: -- The component of the object's position that is parallel to some straight line is proportional to the cosine of (time + a constant).
Since an object moving in uniform circular motion keeps a constant speed there is no force necessary to keep it in motion?
false
What factors affect work?
Work is done when an object moves in the direction in which a force is applied to it. So the factors are the magnitude and direction of the applied force and the factors which affect the object's motion. The latter will include the mass of the object and friction (including drag).
How does an object and motion change in time?
An object's motion can change in time due to various factors such as forces acting on it, acceleration, and the presence of external influences like friction or air resistance. These changes can result in the object accelerating, decelerating, changing direction, or coming to a complete stop. The specific changes in object and motion depend on the particular circumstances and forces involved.
Would there have to be an Unbalanced force acting on moving object?
There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion

What two factors affect the motion of an object?
force, mass
What two factors must be known to determine the velocity of an object in motion?
The object's speed and direction.
The factors that may have effect on the motion of an object?
Force is the only such factor.

false
What type of motion that is force is necessary to make all object accelerate?
heat energy
What two factors affect the motion of an object sliding downhill?
Mass (gravity) & friction!
