False a force at any angle to the direction of motion can not perform work. Power is the rate at which a force is applied.

What happens to the direction of motion of the ball what changes it direction of motion?
A force acting on the ball, at an angle to its line of motion, will cause its direction of motion to change.
What should be the angle between the direction of force and the direction of motion of a body so that the work done is zero?
If the force is perpendicular (at 90 degrees) to the direction of motion, that force does no work.
Force at what direction of motion can perform work?
Work is "defined " as force in the direction of displacement or fdcos(angle), so if the angle is zero the work is maximum. A better definition is to realize that work is the product of force times displacement w=fd= -fdcos(a) + fdsin(A). Here we see that there is real work -fdcos(A)and vector work (commonly called torque) fdsin(A). Notice also that work is negative at angle zero, force and displacement in the same direction and work is positive when the direction is opposite. The differnece in sign is exergy or energy.
Can a force at any angle perform work?
certainly. The force vector can be resolved into one component parallel to the motion of the object under force and another component perpendicular to the motion. The parallel component does the work; the perpendicular component does no work
When force and motion are going in the same direction is work being done?
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.

What should be the angle between the direction of force and the direction of motion of a body so that the work done is zero?
If the force is perpendicular (at 90 degrees) to the direction of motion, that force does no work.
Why force have cosine value?
If a force is acting at an angle to the direction of motion then it is usually helpful to study components of the force along the line of motion and at right angles to it. For a force of magnitude f, acting at an angle x with the line of motion, the component along that line is f*cos(x).

What should be the angle between the direction o foce and the direction of motion of a body so that the work done is zero?
Work is zero when the force is perpendicular to the direction of motion, as it is, for example, in a circular gravitational orbit.
What is the angle between the direction of motion of an object and the direction of the applied force if the work done on the object is said to be negative?
If the angle between force and displacement is between 90 to 270 degree because value of cosine trignometric function is negative within these limits.work=fdcos(angle)
Can a force at any angle perform work?
certainly. The force vector can be resolved into one component parallel to the motion of the object under force and another component perpendicular to the motion. The parallel component does the work; the perpendicular component does no work
If this acts on an object the object will change speed and direction?
You mean a force I guess. A force acting on an object will make it accelerate or decelerate, and if it is acting at an angle to the existing line of motion will make it change direction.
How does the direction of friction compare to the direct motion?
The direction of the force of friction is opposite of the direction of the motion.
How does the direction of frictional force compare to the direction of an object motion?
The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
When force and motion are going in the same direction is work being done?
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
When a force when a force produces motion in the direction of the force?
work
