Is it possible to have a non-zero net force on an object that does no work...
Homework Answers
Yes, it is possible.
When a charge particle undergoes circular motion in the region of external magnetic field, the magnetic force acts as a centripetal force, which is perpendicular to the velocity, therefore the magnetic force doesn't do any work, and there is no change in kinetic energy of the charge particle.

Is it possible to have a negative normal force and if so which direction does the negative force direct the object? If a computer that weighed 25 pounds had a rope tied to it that ran vertically upward over a pulley with a box weighing 50 pounds hanging from the other side would the force that the table exerts on the computer be equal to -25N or is that even possible? Wouldn't the computer accelerate up into the air having...

7. A non-conservative force does 300 of work on an obiect while the object is rolling uphill. During the application of the force the gravitational potential energy of the object increases by 4001 while the rotational kinetic energy decreases by 2001, what is the change in the translational kinetic energy of the object?

The following objects all have a net force of zero Newtons and are therefore in equilibrium. In each case some forces acting on the object are provided. Discuss the total number of forces acting on the object and add the missing forces. You may elect to choose from the provided list of forces, but feel free to discuss/provide a force that is not listed, if you feel your explanation is better. List of possible forces: Weight (The pull of gravity)...
