LESSON SUMMARY (CONCLUSION): Ask Questions Worksheet
5.1 Summarise on the lesson on the Chalkboard
chalkboard Take home work activity summary
Work is done when the force displaces
the object in the
direction of the force.
The SI units of work is Joule (J) which is
equivalent to (N·m)
Work is a scalar quantity with magnitude
only, i.e. No direction
1 joule of work done when a force of 1 N
acts through a
distance of 1 m.
Under frictionless conditions, no work is
done when the object is
moving at a uniform velocity, since no
resultant force is
applied.
If force is applied on an object, and
there is no movement the
magnitude of work = 0 J
