Want this question answered?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
it is speed of motion and direction of motion
If you mean changes, it's acceleration.
Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.
"Acceleration" does not mean "speeding up". Acceleration means any changein the speed or direction of motion. An object with no acceleration moves at aconstant speed in a straight line. If its path is not straight, then the directionof its motion changes, which fits the definition of acceleration.
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
"Acceleration" is the term used to describe motion whose speed, or direction, or both, are changing.
Unbalanced forces are forces that produce a nonzero net force, which changes an object's motion. The result of an unbalanced force is acceleration of an object.

One feels the changes in velocity, or acceleration, when the motion of the vehicle changes.
It is called acceleration.

Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
A force will produce acceleration when the object moves. force in the line of motion will increase the acceleration and the force opposite to the line of motion will decrease the acceleration.
