Yes, work can still be done even if there is no motion. Work is defined as the force applied over a distance, so as long as there is a force acting on an object in the direction of the force, work is being done. If an object is stationary but has a force applied to it, work is still being done even though there is no motion.
Yes, work is being done when force and motion are going in the same direction. Work is defined as the product of force applied in the direction of motion and the distance over which the force is applied. So, when force and motion are in the same direction, work is being 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 the force acting on an object points at least partially in the direction of motion, the work done is considered to be positive. This is because the force is helping to move the object in the same direction as its motion, resulting in a positive work output.
True. When the force is perpendicular to the direction of motion, no work is done because work is the product of force and displacement in the direction of the force. Since there is no displacement in the direction of the force, no work is done.
When a particle is moving in a circular motion at a constant speed, the work done by the particle is zero. This is because work is defined as force applied over a distance in the direction of the force, and in circular motion, the force and displacement are perpendicular to each other, resulting in no work being done.

work
True. When the force is perpendicular to the direction of motion, no work is done because work is the product of force and displacement in the direction of the force. Since there is no displacement in the direction of the force, 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 a particle is moving in a circular motion at a constant speed, the work done by the particle is zero. This is because work is defined as force applied over a distance in the direction of the force, and in circular motion, the force and displacement are perpendicular to each other, resulting in no work being done.
If the angle between the force and the direction of motion of a body is 90 degrees (perpendicular), then the work done is zero. This is because the component of force in the direction of motion is zero, resulting in no work being done on the object.
When a force is perpendicular to the direction of motion, no work is done. This is because work is defined as the product of force and displacement in the direction of the force. If the force is perpendicular, then there is no displacement in the direction of the force and thus no work is done.
Yes, a force can perform work at any angle to the direction of motion. The work done is determined by the component of the force that is in the direction of motion, not the total force itself. This component is what contributes to the displacement of the object and thus the work done on it.
The work done when pushing a crate with a force N across a distance M on a floor depends on the angle between the force and the direction of motion. If the force is applied in the same direction as motion, work done is N * M. If the force is applied at an angle, work done is N * M * cos(theta), where theta is the angle between the force and direction of motion.
