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.

A force at any angle to the direction of motion can perform work?

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.


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.


When a force when a force produces motion in the direction of the force?

work


When a force produces motion in the direction of the force is called?

work


A force acting on an object does no work if?

the force is not in the direction of the objects motion.


What is the exertion of a force on an object called that produces motion in the direction of a force?

Work occurs when a force causes an object to move in the direction of the force.


Occurs when force is applied over a certain distance and motion is in the same direction as the force?

Work. The object doesn't have to be moving in the same direction as the force.If I'm pushing north and the object is moving northeast, then it has a componentof motion in the direction of my force, and I do work.


When force is perpendicular to the direction of motion is work done?

No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.


When force is to the direction of motion no work is done?

No. Only if you are applying the same amount of force then there is no motion. If you are applying more force (the object is moving) then there is work being done.


When the force acting on an objects points at least partially in the blank direction of the motion the work done is considered to be what?

Positive work is work done in the direction of motion, while negative work is work done in the opposite direction from the motion.opposite


Work definition scientifical?

Work = (magnitude of force in the direction of motion) times (distance it moves)
