2. FORCE
Force is generally known as the push and pull
effect. The unit in which force is measured is
Newton (N), this SI unit is also used for
weight.
Weight is the force by which the earth attracts
an object to its centre. In order for weight to
be calculated the MASS of the object must be
known along with the gravitational force
(10N).
3. MATTER
Matter is anything that occupies space and
possesses MASS.
Everything around us consists of matter which
can be made up of three different types of
substances.
The periodic table consists of elements that
have matter and that is why they have MASS
numbers.
4. Mass
Mass is more specifically known as inertial
mass which can be defined as a quantitative
measure of an object's resistance to
the change of its speed.
The SI unit of mass is the kilogram (kg).
Mass is an intrinsic property of that body that
never changes.
5. In order for us to calculate force we ought to
know the MASS of the objects acting on each
other. MASS helps us know how much energy
or force is need to move or pull or lift
objects. MASS of an object is also directly
proportional to its gravitational force it has
on other objects
6. MASS in Force is very important and so is it in
matter. As mentioned in the third slide all
matter has MASS and in chemistry we work on
the properties of matter. MASS of an object
influences the temperature needed for the
object for it either to melt or evaporate or be
a solid.
7. Compare the mass of a compound, element
and object with its melting points. Then see
the relation.
8. This experiment is even easier. Take a
basketball that is deflated and put it on a
scale. Record the weight and then pump up
the basketball until it bounces correctly. Now
weigh the ball a second time. It will weigh
more now that it has air in it.
9. ACTIVITY 1
I will ask the learners to calculate their weight
on different plants so they can see that their
mass is dependent on the force of gravity. I
will give them a sheet of the gravitational
forces of other planets in which they must
multiply their earthly mass with
10. ACTIVITY 2
Calculate the different weights of the
elements on the periodic table and also the
weight of some compounds formed by the
elements using their mass.
11. THERE IS ALWAYS A CONNECTION BETWEEN
PHYSICS AND CHEMISTRY ONE JUST ALWAYS
NEEDS TO LOOK DEEP INTO THEIR
SIMILARITIES AND UNDERSTAND THAT THE
TWO STRANDS STILL FALL UNDER ONE
SUBJECT... WHICH IS SCIENCE.
