This document defines different types of forces and energy. It describes 9 types of forces: frictional, normal, magnetic, air resistance, applied, spring, gravitational, electrical, and tension. It explains that force is a push or pull on an object. It then defines 7 types of energy: sound, wind, light, kinetic, potential, and heat. Force and energy allow things in the world to function and change. Force causes motion or tries to stop motion while different forms of energy underlie everyday phenomena and power technologies.

5. FRICTIONAL FORCE




Friction is a force that is
created whenever two
surfaces move or try to
move across each other.
Friction always opposes the
motion or attempted motion
of one surface across
another surface.
Friction is dependant on the
texture of both surfaces.
Friction is also dependant
on the amount of contact
force pushing the two
surfaces together

6. NORMAL FORCE


A force acting perpendicular
to two surfaces in contact
with each other. It is a
measure of the force
holding the two surfaces
together. The larger the
normal reaction force, the
larger the value of limiting
friction. It is the
measurement of force
against an object,
otherwise, the friction
created. It cannot enter the
object or become part of the
object or surface.

7. MAGNETIC FORCE

A magnetic force is a
type of field force whose
potential and momentum
energy is at the expense
of an electrical field in
time. It can be observed
when a magnetised metal
comes into contact with
to another magnetised
material. This force is
usually measured in
Newton's and its direction
is given by the right hand
rule.

8. AIR RESISTANCE FORCE

Air resistance refers to
a force that acts
against relative motion
of an object through a
liquid or gas. It is also
known as drag and
acts in an opposite
direction to the
oncoming velocity.

9. APPLIED FORCE

Applied force is a term
that is defined as a
surface force or body
force that acts on an
object. The force is
typically applied to an
object either by a
person or by another
object. This term is
usually used in
physics.

10. SPRING FORCE

The spring force is the force
exerted by a compressed or
stretched spring upon any
object which is attached to
it. An object which
compresses or stretches a
spring is always acted upon
by a force which restores
the object to its rest or
equilibrium position. For
most springs, the magnitude
of the force is directly
proportional to the amount
of stretch or compression of
the spring.

11. GRAVITATIONAL FORCE

Gravity is a force that
attracts all objects or
masses to each other.
Gravity is responsible
for making Earth
revolve around the Sun
and the Moon around
the Earth.

12. ELECTRICAL FORCE

An electrical force is
something that exerts a
force on another. If the
charges are the same,
the items will push
away from each other.
If the charges are
different, then the items
will be attracted to
each other.

13. TENSION FORCE

Tension force is the
force that is supplied
by strings, chains and
ropes. Tension forces
are applied by pulling
and are always
directed along the
length of the thing that
is being pulled. Tension
force is the opposite of
compression force.

14. WHAT IS ENERGY

Look around you. Is anything moving?
Can you hear, see or feel anything? Sure... this is
because something is making something happen,
and most probably, there is some power at work.
This power or ability to make things happen is what
we can call energy. It makes things happen. It
makes change possible.

16. SOUND ENERGY

Sound energy refers to the energy generated by
sound vibrations as they travel through a specific
medium. This form of energy is also associated with
disturbance of matter. Therefore sound energy is a
form of mechanical energy.

17. WIND ENERGY
Wind energy is power that has come from the wind. Often
times, a windmill is used to harvest wind energy to generate
electricity. Wind energy is considered to be a renewable
resources and a clean source of energy.

18. LIGHT ENERGY
Light energy can be described as the potential of work that is
inherent from light. It can also be viewed as a means by
which electromagnetic radiation is perceived from the natural
light sources e.g. the sun to living things. This energy is
carried in discrete packets called photons i.e. In living plants
for example, the light energy is what splits organic molecules
to make chemical energy in a process called photosynthesis.

19. KINETIC ENERGY
Kinetic energy is the energy that is generated within an
object that is in motion. The magnitude of this energy is
directly proportional to the mass of the object and the
square of the velocity of this moving object.

20. POTENTIAL ENERGY
Potential energy is a stored or reserved energy in an object.
This form of energy has a potential to work and is powered
by the gravity. The scientific formula for potential energy is
actually due to gravity.

21. HEAT ENERGY
Heat energy is a form of energy that results from movement
of atoms, ions or molecules in solids liquids or gases. It can
be transferred from one object to another if the two objects
have a temperature difference.
