EmSAT Physics Achieve
(General Track)
Total Time for Test: 1.5 hour EmSAT Physics Achieve (Advanced Track) is a computer‐based test and has 4 major sections – Physics Foundations, Energy‐ Transmission, Energy ‐ Waves, Force and Motion‐Objects. Test sections, questions, and options are randomized. Sections and subsections of the test are timed by the computer. Test takers can see how much time they have throughout the test. Part 1: Physics Foundations ‐ Able to recognize vector quantities use them to solve problems
Solve problems using scalar multiplication of vectors
Solve problems using addition or subtraction of vectors
Solve problems using linear combination of vectors
Translate a vector Find the magnitude of a vector
Calculate the magnitude and direction of a vector
Find the dot product Find the angle between two vectors Use the dot product to find perpendicular
vectors
Find the components of a vector
Find the component of a vector along another vector

Part 2: Energy‐Transmission ‐ Describe transmission of various forms of energy
o Understand that heat moves in
predictable ways, flowing from warmer
objects to cooler objects until both reach
the same temperature
o Know that heat can be transferred
through matter by the collisions of
atoms and/or molecules (conduction) or
through space (radiation)
o Understand during a phase change, heat energy is absorbed or released
o Understand that most substances expand when heated and contract when cooled
o Know that temperature affects the solubility of some substances in water
o Know the energy cannot be created or destroyed, but only changed from one form into another
o Understand that energy can change
from one form to another, although in
the process some energy is always
converted to heat
o Understand all energy transfers are governed by the law of conservation of energy
o Understand that energy may be converted among mechanical, electromagnetics, nuclear, and thermal forms
o Know that potential energy is the energy
an object possesses by its position or
condition such as gravitational and elastic o Know that kinetic energy is the energy an
object possesses by its motion o Understand an ideal mechanical system is
the sum of the macroscopic kinetic and potential energies is constant
o Understand when work is done or by a system, there is change in the total energy of the system
o Understand that work done against friction results in an increase in the internal energy of the system
o Know that power is the time‐rate at which work is done or energy is expended

Part 3: Energy‐Waves ‐ Explain variations in wavelength and frequency in terms of the
sources of the vibrations that produce them, e.g., molecules, electrons, and nuclear
particles
Know that different forms of electromagneticenergy have different wavelengths
Understand that light passes through some materials, sometimes refracting in the process
Know that electrical energy can be produced
from a variety of energy sources and can be
transformed into almost any other form of
energy Know that electrical circuits provide a means of transferring electrical energy
Understand that material that has been
electrically charged attracts uncharged
material, and may either attract or repel
other charged material Know that a magnet attracts certain materialsand either attracts or repels other magnets
Know that an oscillating system produces waves
Know that waves carry energy and information without transferring mass
Understand that waves incorporate the characteristics of amplitude, wavelength, frequency, period, wave speed, and phase
Know that mechanical waves require a material medium through which to travel
Understand that waves are categorized by the direction in which particles in a medium vibrate about an equilibrium position relative to the direction of propagation of the wave
Know that resonance occurs when energy is transferred to a system at its natural frequency
Know when a wave strikes a boundary between two media, reflection, transmission, and absorption occur
Know the absolute index of refractions is inversely proportional to the speed of a wave
Know all frequencies of electromagnetic radiation travel at the same speed in a vacuum
Know diffraction occurs when waves pass by obstacles or through openings
Understand when waves of similar nature meet, the resulting interference may be explained using the principle of superposition
Understand when a wave source and an observer are in relative motion, the observed frequency of the waves traveling between them is shifted

Part 4: Force and Motion‐Objects ‐ Explain and predict different patterns of motion of objects
(e.g. linear and uniform circular motion, velocity and acceleration, momentum and inertia)
Know the motion of an object is alwaysjudged with respect to some other object or point
Know the motion of an object can be described by its position, direction of motion, and speed
Understand an object's motion is the result of the combined effect of all forces acting on the object
Know that force is directly related to an object's mass and acceleration

Understand that machines transfer mechanical energy from one object to another
Know that Friction is a force that opposes motion
Understand that a machine can be made more efficient by reducing friction
Understand that machines can alter
the direction or amount of force, or
the distance or speed of force
required to do work Understand the basic differences
between simple and complex machines Understand that an object in linear
motion may travel with a constant velocity or with acceleration
Understand that an object in free fall accelerates due to the force of gravity
Know the path of a projectile is the
result of the simultaneous effect of
the horizontal and vertical
components of its motion
Understand that a projectile's time inflight is dependent upon the vertical components of its motion
Know the horizontal displacement of
a projectile is dependent upon the
horizontal components of its motion

directly proportional to its mass (NFL) Know when the net force on a system
is zero, the system is in equilibrium Understand an unbalanced force
causes a mass to accelerate (NSL) Know weight is the gravitational force
with which a plant attracts a mass Understand the elongation or
compression of a spring depends
upon its spring constant and the
