# Can you exert a force on an object without doing work?

## Can you exert a force on an object without doing work?

If there is no motion in the direction of the force, then no work is done by that force. It changes the direction of the motion, but it does no work on the object. This can be applied to any circular orbit.

How can a very large force applied to an object do not work?

If a force is applied but the object doesn’t move, no work is done; if a force is applied and the object moves a distance d in a direction other than the direction of the force, less work is done than if the object moves a distance d in the direction of the applied force.

### What happens when you exert a force on an object?

As you exert a force on the object, the ground exerts a frictional force on the object resisting motion. Since the object doesn’t accelerate, that means the vector sum of the two forces is 0.

When is force expended there is no work done?

1.) As you assumed, since the object does not move any distance, then by the definition of work, no work is done and thus the statement is true – no matter how much force is exerted, if there is no displacement, no work is performed. 2.) If a person exerts a large force on an object and the object does not move, there is no external work done.

#### Is it possible to exert force on a stationary body?

Take the help of Newton’s first law which says that an object would be at rest or would move at a constant velocity if there is no net force acting on the body. It is possible to exert force on a stationary body because force is a push or pull.

Is it possible to exert a force that does not move?

It is possible to exert a force on a body that doesn’t move if the resultant of that force together with all the other forces acting on the body sum to zero. (P.S. Michigan….GO BLUE) force is defined as mass * acceleration. From the well known hyperphysics web site: The net external qualification is crucial.
