Work

Work is done when a force is applied to an object and the object moves in a direction of the applied force.

Force x distance is the simplest way to define work

This is measured in a Joule

Have you heard of Joules before?

If you said yes to the previous question you would be right. Much like with forces angles need to be factored in

Also much like net forces work can be negative, positive, or zero

They also can be added

You slide a .12 kg coffee mug .15m across a table. The force you exert is horizontal and of magnitude .10 N. The coefficient of kinetic friction between the mug and the table is .05 . How much work is done on the mug

A farmhand pushes a bale of hay 3.9 m across the floow of a barn. She exerts a force of 88 N at an anle of 25 degrees below the horizontal

To move a suitcase up to the checkin stand at an airport, a student pushes with a horizontal force through a distance of .95 m. If the work done by the students is 32 J, what is the magnitude of the force he exerts?
