EST Two- about physics and raw score

About EST physics

EST physics exam includes 75 questions with a decent raw score in EST Two. The main topics in physics (EST2)

Mechanics – Electricity- Waves & optics – Heat & thermodynamics and finally atomic and nuclear physics

One of the best advantages is the raw score

0 out of 75     400/800

15 out of 75    500/800

30 out of 75     600/800

45 out of 75     700/800

60 or above    800/800

Mechanics– EST Physics

Is the physics of motion, the principles of physical laws and their effect on the behavior of objects.  It includes statics, kinematics (motion), dynamics (forces), energy, gravity and momentum

Electricity EST Physics

It includes static electricity, dynamic electricity, electromagnetism and simple electronic circuits

Waves & optics– EST Physics

Is the study of simple harmonic motion, types and properties of waves, geometric and physical optics .

Heat & thermodynamics – EST physics

Is the study of thermal systems, Ideal gases, heat transfer in addition to first and second laws of thermodynamics and heat engines

Atomic and nuclear physics – EST physics

It includes photoelectric effect, work function and atomic theory

Nuclear physics studies subatomic particles, radioactive decay and mass-energy equivalence

Graphic variables

Y = (constant)X.

This means that the speed increases linearly with time.

In general, a linear relationship exists between two quantities that form a straight line on a graph. Notice the visual impact of a graph.

In this case, the graph is not linear. The upward-curving shape shown on the graph is a parabola. This shape indicates that the position depends on the time squared

Y = (constant)X2

EST 2 physics

Y = (constant)X½

This relationship is inverse. In an inverse relationship, as one quantity gets larger, the other gets smaller. In this case, P = constant/V

Y = (constant) / X

Important Notes about the graphs

Slope is calculated by dividing rise by run, means the difference between any two point on Y-axis by the difference on X-axis.

• The unit of slope is the same unit of unit of Y-axis /unit of x-axis.

The area of the graph is calculated by (length × width ) for rectangle and (½ × base × height) for triangle.

• The unit of area is the same unit of Y-axis × unit of X-axis.

Coordinate System

• A frame of reference is referred to as a coordinate system.

• A coordinate system in one dimension is represented by an x axis with the origin located at x = 0.

 The most common prefixes in SI units and their symbols in the form of power of 10 are shown in the table.
