free fall motion (benda jatuh bebas), free fall is a special type of motion in which the only force acting upon an object is gravity, It is a motion under influence of gravity alone.
from picture above we can consider that acceleration of earth gravitation is constants, Free fall motion is the motion in a vertical direction as seen by an observer on the Earth’s surface.

Force and Its Representation, A force is a push or pull acting upon an object as a result of its interaction with another object,in physics, force is what causes a mass to accelerate. It may be experienced as a lift, a push, or a pull. The acceleration of the body is proportional to the vector sum of all forces acting on it (known as the net force or resultant force
contact force types
- Frictional Force
- Tension Force
- Normal Force
- Air Resistance Force
- Applied Force
- Spring Force
and Action at a Distance Forces are
- Gravitational Force
- Electrical Force
- Magnetic Force

at physics test sheet UMPTN or now called SPMB begin with acceleration (percepatan) test, energy of kinetic movement, equilibrium of mass,amplitude and period, now at this post let’s learn about acceleration, Test sheet you should dawnload at last of post.
Acceleration shows the change in velocity in a unit time. Velocity is measured in meters per second, m/s, so we can says that acceleration is measured in (m/s)/s, or m/s2, which can be both positive and negative, when positive is more faster, but when the value negative is more slower, we can explain by simple matematic simbol that
where v is velocity, d is displacement and t is time.
where a is acceleration, v is velocity and t is time.
then An average acceleration, or acceleration over time, ? can be defined as
for the circular motion we have
it’s simple right, now try to answer the question in sheet below , first you must download it

at physics test sheet UMPTN or now called SPMB begin with kalori meter, than optic ,force and mass relation, mono atomic pressure relation and wave,de brogie wave,
now let’s learn about newton law, In classical mechanics, acceleration a is related to force F and mass m (assumed to be constant) by way of Newton’s second law:
now let’s learn about wave spesialy for period of wave
The period of a wave is the time the full wave takes to pass a given point. The period, T and the frequency f obey the following relation
where f is the frequency of the wave, measured in inverse seconds (s-1 or hertz (Hz)) and T is the period, measured in seconds.
Since 
then
they are the formula about periode in wave, now you can learn more by downloading test sheet UMPT,SPMB below

in 1976, ITB - Bandung Institute of Technology , located in Bandung, have their own test that conduct to screening Senior High school student who want to enter the university, this Physics test sheet is one of them,
this sheet contains 36 number of problem , they are abouts : PT diagram for water, conductor and isolator material , frequencies , radiation of radioactive material, light, lens and mirror, mechanical structural principle by using newton law, momentum and others
now we give a litle tutorial about conductor
Heat conduction or thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and hence acts to even out temperature differences.
in electricity Conduction is the movement of electrically charged particles through a transmission medium (electrical conductor)

at this test of spmb still about Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light)
The study of light and the interaction of light and matter is termed optics. then optic The observation and study of optical phenomena such as rainbows and the Aurora Borealis offer many clues as to the nature of light as well as much enjoyment.
other test about mechanism , A mechanism is some technical aspect of a larger process or mechanical device, a part or combination of parts designed to perform a particular function,The scientific definition of a machine is any device that transmits or modifies energy. In common usage, the meaning is restricted to devices having rigid moving parts that perform or assist in performing some work and then about kinetics Kinematics (Greek ??????, to move) is a branch of mechanics which describes the motion of objects without the consideration of the masses or forces that bring about the motion. By contrast, dynamics is concerned with the forces and interactions that produce or affect the motion
then dynamical test,dynamics is the branch of classical mechanics that is concerned with the effects of forces on the motion of objects. The former distinguishes it from kinematics and the latter distinguishes it from statics. In quantum physics, dynamics may refer to how forces are quantized, as in quantum electrodynamics or quantum thermodynamics’s.

The nitrogen cycle represents one of the most important nutrient cycles found in terrestrial ecosystems (Figure 9s-1). Nitrogen is used by living organisms to produce a number of complex organic molecules like amino acids, proteins, and nucleic acids. The store of nitrogen found in the atmosphere, where it exists as a gas (mainly N2), plays an important role for life. This store is about one million times larger than the total nitrogen contained in living organisms. Other major stores of nitrogen include organic matter in soil and the oceans. Despite its abundance in the atmosphere, nitrogen is often the most limiting nutrient for plant growth

Sound is what can be perceived by a living organism through its sense of hearing.[1] Physically, sound is vibrational mechanical energy that propagates through matter as a wave, The Nature of a Sound Wave can divided into
a. Sound is a Mechanical Wave
b. Sound is a Longitudinal Wave
c. Sound is a Pressure Wave
For humans, hearing is limited to frequencies between about 20 Hz and 20000 Hz
mechanical wave and electrical wave is different, Electromagnetic waves are waves which have an electric and magnetic nature and are capable of traveling through a vacuum. Electromagnetic waves do not require a medium in order to transport their energy. Mechanical waves are waves which require a medium in order to transport their energy from one location to another.
