What is the equation used to calculate work done by a force on an object?
Work done = force × distance (W = Fs)
What are the units for work done, force, and distance, respectively?
Work done is in joules (J), force is in newtons (N), and distance is in metres (m).
How much work is done when a force of one newton causes a displacement of one metre?
One joule of work is done.
What is 1 joule in terms of newton-metres?
1 joule = 1 newton-metre.
What happens to an object when work is done against frictional forces?
It causes a rise in the temperature of the object.
When does a force do work on an object?
When the force causes a displacement of the object.
what is work done
the energy transferred when a force causes an object to move a certain distance
