         Yesterday, we talked about Newton’s 3rd When an object exerts a force on another
         law of Motion which is the law of object, the second object exerts on the first a
         interaction. What does it state?        force of the same magnitude but in opposite
                                                 direction.
         That is correct! Or simply, for every         (A student answers)

         Very good! Walking is possible because
         of the 3rd law of motion. It seems like you
         already      mastered      our    previous

Work have different meanings to
different people. But in physics, work has
a very specific meaning. Refer to the

EXPLAIN   Work is done when the force (F) applied
          to the object causes the object to have a
          displacement (d) in the same direction as
          the force applied. The symbol for work is
          a capital W. The work done by a force
          can be calculated as
                           W = Fd

            Take note that heat is also a form of
            energy, in other words, energy is
            transferred from the coffee cup to the
            metal spoon.
            Work is also a means of transferring
            energy from one object to another. Refer (A student answers)

            Try to imitate the illustration at your
home (use plastic bottle and a small ball),
give a nudge on the ball and see what
happens.
If you notice, after pushing the ball it
continuously move until it hits the plastic
bottle. Something was transferred from
your hands to the ball causing it to move
continuously. That something is called
“energy”.
Since work is done on the ball, it gains
energy while the person that does work
on it loses energy. How about in the case
of ball and the plastic bottle?
What relationship can you infer between
work and energy based on the illustration
that has been discussed?
