What is the work done by a force when the force is?

To calculate the work done on an object when a force moves it, use the equation: work done = force × distance. This is when: work done is measured in joules (J) force is measured in newtons (N)

Why does a force do work?

A force is said to do work when it acts on a body so that there is a displacement of the point of application in the direction of the force. Thus, a force does work when it results in movement.

What are the conditions of work done to be zero?

Zero work is done when the displacement of a body is zero or perpendicular (θ=900,cosθ=0) to the direction of force applied, then work done is zero. For example, if a person tries to push a wall, he is applying force yet the wall does not move, so the displacement of the wall is zero, and hence work done is zero.

What is the work done by a force when the force is :- i normal to the displacement produced II in the same direction as the displacement produced?

Answer Expert Verified Work done is defined as product of force and displacement. (i) normal to the displacement produced. Workdone in this case is zero because both Force and displacement are perpendicular to each other. =0 as cos 90° is zero.

What is the work done by a force when the force is in the same direction as the displacement?

The work done by a force is zero if the displacement is either zero or perpendicular to the force. The work done is positive if the force and displacement have the same direction, and negative if they have opposite direction.

What is meant by variable force?

[′ver·ē·ə·bəl ′fȯrs] (mechanics) A force whose direction or magnitude or both change with time.

Is work force times distance or displacement?

If I carry an object to and fro 10 metres, the work done would be Force x 20 metres. If I carry an object to and fro 10 metres, the work done would be Force x 0 metres.

What is meant by zero work?

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.
