can normal force do work?
13323
At the first-year physics level -- absolutely a normal force can do work. If an object moves parallel (or antiparallel) to a normal force, then the normal force has done work. ... The normal force is upward, movement is left, so the motion is not parallel to the normal force. No work is done by Fn.

There are 2 types of forces, contact forces and act at a distance force. Every day you are using forces. Force is basically push and pull. When you push and pull you are applying a force to an object.

False - Forces, if unbalanced, can cause objects to accelerate (one form of moving; the other form is moving at a constant velocity). But by no means can one say that forces always cause objects to move.

Explanation: Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force).

Normal force is a contact force. If two surfaces are not in contact, they can't exert a normal force on each other. ... It makes sense that the force is perpendicular to the surface since the normal force is what prevents solid objects from passing through each other.

ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero. example: When we hold an object and walk,the force acts in downward direction whereas displacement acts in forward direction.

If a body is under the action of a force that does no net work during any closed loop, then the force is conservative. If work is done, the force is nonconservative.

Work = Mass * Gravity * Height and is measured in Joules. Imagine you find a 2 -Kg book on the floor and lift it 0.75 meters and put it on a table. Remember, that “force” is simply a push or a pull. If you lift 100 kg of mass 1-meter, you will have done 980 Joules of work.

The force and distance must be parallel to each other. Only the component of the force in the same direction as the distance traveled does any work. Hence, if a force applied is perpendicular to the distance traveled, no work is done. The equation becomes force times distance times the cosine of the angle between them.

3 Answers. The coefficient of friction should in the majority of cases, remain constant no matter what your normal force is. When you apply a greater normal force, the frictional force increases, and your coefficient of friction stays the same.

Once you apply a force to an object, it will move. ... If the answer is zero, as in one force pulling one way and the other pulling the opposite direction exactly, then those forces will basically cancel each other out. So yes, forces will always result in motion, unless there is another force exactly opposed to it.

When a force is used to move an object, energy is transferred (because the object has moved) and we say that Work is Done. A Force that causes movement in the direction of the force has DONE WORK. The bigger the force that is used, or the greater the distance moved, the greater the amount of Work is Done.

The work you do on a machine is called the work input. The force you apply to the machine to do the work is the input force. The work done by the machine on another object is called the work output. The force the machine applies to do this work is the output force.

Magnetic force, Electrostatic force, Gravitational force etc. Force of friction is not a conservative force since the work done by it depends on the path taken.

Torque is not a force. You can say there is a torque caused by normal forces, but there is no special name for that. A normal force comes from acting with a force on an object resting next to a surface. ... A torque is always parallel to the axis of rotation, so every torque is just as normal as any other torque.

In physics, work is the product of force and displacement. A force is said to do positive work if (when applied) the force has a component in the direction of the displacement of the point of application.
