What else can I help you with?
When force is perpendicular to the direction of motion no work is done ture or false?
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 force is and what direction of motion no work is done?
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.
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 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.
A force acting on an object does no work if?
the force is not in the direction of the objects motion.
What is the work done by a body moving along a circular path?
The work done by a body moving along a circular path is zero if the force is perpendicular to the direction of motion, such as in the case of centripetal force. This is because the displacement is perpendicular to the force. If there is a component of the force in the direction of the motion, work is done, calculated as the dot product of the force and displacement vectors.
When force is perpendicular to the direction of motion no work is done ture or false?
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.

A force acting on an object does no work if?
the force is not in the direction of the objects motion.
What is the work done by a body moving along a circular path?
The work done by a body moving along a circular path is zero if the force is perpendicular to the direction of motion, such as in the case of centripetal force. This is because the displacement is perpendicular to the force. If there is a component of the force in the direction of the motion, work is done, calculated as the dot product of the force and displacement vectors.
When does a force applied to an object not do any work?
A force does not do any work on an object when the object does not move in the direction of the force or when the force is perpendicular to the direction of motion. Work is only done when there is displacement in the direction of the force.
How much work is done when a vertical force acts on an object horizontally?
It depends on the magnitude of the force and the mass of the object
How much work is done by the normal force in a given scenario?
The work done by the normal force in a scenario is zero, as the normal force is perpendicular to the direction of motion and does not contribute to the displacement of the object.
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.
When force and motion are going in the same direction is work being done?
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.
What is the work done against the gravity when a body is moved horizontally along a frictionless surface?
No work is done against gravity when a body is moved horizontally along a frictionless surface because the force of gravity acts perpendicular to the direction of motion. Work is only done when a force is exerted in the direction of motion.
Is it possible that a body be in accelarated motion under a force acting on a body yet no work is being done by the force?
Yes, that is possible. For example, an object in circular motion, accelerated towards the center. The force (and the acceleration) is normal (perpendicular) to the movement; thus, the dot product between the force and the displacement is zero.
