322. Work
Replace the switch (62) with the reed switch (83) in project #317. Hold
the magnet (7) near the reed switch (83) and you will hear the sounds
of a police siren from the speaker (93). Also, you will see the heart LED
(69) is ashing at the same time. In physics, work is done when a force
moves an object.
323. Formula for Work
Connect points C and D with a 4-wire (4) in project #322. Hold the
magnet (7) near the reed switch (83) and you will hear gun shots and
the heart LED (69) will ash at the same time. The formula for work is
W = F*d, where W = work, F = force, and d = distance.
324. Newtons
Connect points A and B with the 4-wire (4) in project #322. Hold the
magnet (7) near the reed switch (83) and you will hear a re siren and
the heart LED (69) will ash at the same time. The Newton is the unit of
measurement of force. One Newton is the force needed to accelerate
one kilogram of mass at a rate of one m/s
2
in the direction of the
applied force.
325. Newton’s Second Law of Motion - Force
Connect points E and F with a 4-wire (4) in project #322. Hold the
magnet (7) near the reed switch (83) and the sounds of space battle
will turn on with the heart LED (69) will ash at the same time. Based
on Newton’s second law of motion, the force on an object is related
to it’s mass and acceleration. Specically, Force = mass*acceleration
(F=m*a).
326. Mass
Connect points G and H with a 4-wire (4) in project #322. Hold the
magnet (7) near the reed switch (83) and you will hear music and the
heart LED (69) will ash to the music. Mass is measure of the amount
of matter that an object is made of. Mass can also be thought of as the
resistance to acceleration (which is the rate of change in the objects
velocity) when a net force is applied.
