| A woman lifts her 100-N child up 4 meters. How much work does the woman do? | 400J |
| You pull your sled through the snow a distance of 500 meters with a force of 200 Newtons. How much work did you do? | 100,000J |
What work do they do in the force?
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.
Which represents the unit for work?
In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule is the unit of work.
What is the unit of work that a role may be asked to perform?
The SI unit of work is joule (J). Joule is defined as the work done by a force of one newton causing a displacement of one meter.
What is work according to Science and write its units?
Work done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force. We define work to be equal to the product of the force and the displacement. Work done = force × displacement. W = F × s. 1J=1N×1m.
How much work is done by a crane that lowers 1000 N?
Work= 150000 Joules. So, the work done by crane that lowers 1000 Newton’s of a material a distance of 150 meters is 150000 Joules.
How is work done measured?
work done is measured in joules (J) distance moved along the line of action of the force is measured in metres (m)
