Acceleration is the change in distance over time True or false?
False. Acceleration is a change of speed or direction over time.
Does Motion occurs when there is a change in speed true or false?
true
Both speed and acceleration include the direction of an objects motion true or false?
This is not true. Acceleration includes direction, but speed does not. Speed in a particular direction is called velocity.
Is it true or false that balanced forces can change an object's direction?
It is false. Change of direction is acceleration, which can only be produced by unbalanced forces.
Acceleration will only speed up an object True or false?
False. At least the way "acceleration" is described in physics, acceleration involves any change in velocity - so the "accelerating" object can speed up, slow down, or simply change direction.

True or false if you know an objects mass and acceleration you can determine the net force being exerted on the object?
False. You will know nothing at all about any force acting perpendicular to the direction of motion.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
Is it true or false balanced force cause a change in motion?
though different terminology is used. Motion is thought of in acceleration and velocity. Now, velocity is just the distance covered over an amount of time, or speed. Acceleration is the change in speed. In general terms, any object that is standing still is being acted upon by equal and opposite forces, and if one of those forces was changed, then the object would undergo acceleration. Think of a person holding a coffee cup. Gravity is working on the object to pull it down, and his or her arm is pulling equally in the opposite direction to keep it up. If the person were to let go, there wouldn't be the upward force, and the cup would accelerate towards the Earth, and its "motion" would be changed. TRUE!
Acceleration is a vector quantity true or false?
True
The motion of giant wheel is a rotatory motion is true or false?
it is false
Is Acceleration is the magnitude of average velocity true or false?
False
Acceleration is a vector quantity?
no, acceleration is not a vector quantity. its false
