What has to be changed in order for acceleration to change?
Since a = F / m, to change a, there must be a change either in the net force applied on the object or in the mass of the object.
What is the effect on the projectile motion when the diameter of the object is changed?
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
To start or change the motion of an object do you need unbalanced force or balanced force?
Doesn't matter Balanced Force would mean the object is traveling at a constant velocity due to Newton's First Law of Motion (Law of Inertia) Unbalenced Force would mean the object is accelerating (or decellerating) due to Newton's Second Law of Motion
What must happen for an obect at rest to move or change its speed?
A force must be applied to that object according to Newton's First Law of Motion in order to change the speed and its direction.
What is the definition of resistance to acceleration?
Inertia resists acceleration. Inertia resists a change in the state of motion of a particle or rigid body. For instance, in order for the state of motion of an object to change, there must be a net external force exerting on the object, which is defined as mass times acceleration. Resistance to this net external force would therefore have to resist the object's acceleration, and that is inertia.
What is needed in order to cause an object at rest to move or an object in motion to change the direction and speed?
A force.
What is needed in order to cause an object at rest to move or an object you motion to change its deirection or speed?
An unbalanced force.
What is needed in order to cause an object at rest to or an object in motion to change its direction or speed?
An outside force to act on it

How does inertia affect the speed of an object?
Inertia is the tendency of an object to resist a change in its motion. Objects with more mass have more inertia. The more mass an object has the harder it is to change its motion. Thats is how inertia effects and object. (Don't worry I got this from my Science Textbook)

In order to put an object in motion horizontallyit has to be given energy true or false?
Yes, this is correct. In order for the object to move, it has to be given energy by force.
